The world has known many kinds of war—the Hundred Years War and a “hundred-hour war,” the Seven Years War and the Six Day War, cold wars and phony wars, great wars and “splendid little wars.”[i]

Whatever one’s view of war, the hard truth is that war is part of humanity. It can be limited or deterred. But it cannot be outlawed like some crime because there’s no consensus on who should play the role of judge—and there’s waning interest in the role of sheriff. Nor can it be cured like some disease because of the very nature of man, as some of history’s greatest thinkers have concluded. “There is a time for war and a time for peace,” as Solomon wrote.  Yet America’s generals are seldom so matter-of-fact about war. Sherman called war “hell.” Lee said it was “terrible.” Eisenhower deplored war for “its brutality, its futility, its stupidity.”

Drawn from various open-source materials, including the Congressional Research Service (CRS), Congressional Budget Office (CBO), Defense Department, Smithsonian Institution, Veterans Museum and Memorial Center, and media outlets, the following is by no means an exhaustive catalog. After all, a CRS index of U.S. military intervention tallies some 330 “notable deployments of U.S. military forces overseas” since 1798.[ii]This list does not include, for instance, a myriad of limited military engagements—blockades, humanitarian airdrops, rescue operations in Iran and Syria, raids on Libya and Iraq, drone strikes in Yemen and Somalia. But by highlighting the vital statistics of America’s most consequential and/or costly military engagements, it traces war’s impact on America.

Revolutionary War, 1775-1783

U.S. military deaths: 4,435

U.S. wounded: 6,188[iii]

Cost: $101 million in 1770s dollars

The 4,435 war deaths represent almost 0.2 percent of the population at the time.[iv]While the U.S. didn’t technically have a GDP in 1775, we can get a sense of the war’s enormous economic costs by extrapolating from U.S. GDP in 1790, when the nation’s wealth totaled $189 million.[v]

Barbary Wars, 1801-1805 and 1815

U.S. military deaths: 35

U.S. wounded: 64[vi]

In 1795, the U.S. paid almost $1 million to ransom 115 sailors.[vii]Thomas Jefferson bitterly opposed this policy, and overturned it as president, declaring, “It will be more easy to raise ships and men to fight these pirates into reason, than money to bribe them.”[viii]

War of 1812, 1812-1815

U.S. military deaths: 2,260

U.S. wounded: 4,505

Total serving: 286,730

Cost: $90 million (2.2 percent of GDP in peak year)[ix]
After defeating the British Empire less than 30 years earlier, the young republic was soundly swatted back into place in 1812. U.S. forces were routed in Canada, U.S. vessels seized, U.S. ports blockaded, the U.S. Capitol and White House set ablaze. Congress declared war against Britain in June 1812.

Indian Wars, 1813-1838 and 1866-1890

U.S. military deaths: 1,000[x]

Total serving: 106,000

We know that some 4,000 Cherokee died during their forced westward migration in 1838.[xi]But estimates range wildly as to the number of Native Americans who died in the frontier wars.[xii]

Mexican War, 1846-1848

U.S. military deaths: 13,283 (1,733 battle deaths)
U.S. wounded: 4,152

Total serving: 78,718

Cost: $71 million (1.4 percent of GDP in peak year)

To bring pressure on Mexico, President James Polk sent Gen. Zachary Taylor to a disputed area between the Rio Grande—where the U.S. defined the border—and the Nueces River—where Mexico defined the border. To Mexican troops this was aggression, and they attacked Taylor’s forces. Congress declared war against Mexico in May 1846.

Civil War, 1861-1865
Union military deaths: 364,511 (140,414 battle deaths)
Union wounded: 281,881
Confederate military deaths: 133,821
Union cost: $3.18 billion (11.3 percent of GDP in peak year)
Total serving: 2,213,363 (Union); 1,082,119 (Confederate)[xiii]

Spanish American War, 1898

U.S. military deaths: 2,446 (385 battle deaths)

U.S. wounded: 1,662

Cost: $283 million (1.1 percent of GDP in peak year)

Total serving: 306,760

Long before U.S. forces rescued post-tsunami Sumatra, triaged postwar Bosnia, fed Somalia, protected Kosovo and Kurdistan, defended Libyans from Kaddafi or Yazidis from ISIS, President Theodore Roosevelt argued against “cold-blooded indifference to the misery of the oppressed.”[xiv]Even when “our own interests are not greatly involved,” he declared, “action may be justifiable.”[xv]The American people took such action as Spain crushed Cuban independence efforts—arguably America’s first humanitarian war. Of course, the war also had strategic implications, as Washington used Spain’s mistreatment of Cuba as a pretext to move against Spanish possessions in the Philippines, Puerto Rico and Guam. Following the sinking of the Maine, Congress declared war in April 1898.

Philippines, 1899-1901

U.S. military deaths: 4,200

U.S. wounded: 2,800[xvi]

Total serving: 120,000

Not unlike the Iraq War a century later, the postwar occupation of the Philippines would lead to an insurgency that proved far bloodier than the initial conflict.

Mexico, 1914-1919

U.S. military deaths: 21

U.S. civilian deaths: 35[xvii]

U.S. forces deployed: 6,000

Supporting anti-government revolutionaries inside Mexico, President Woodrow Wilson ordered U.S. troops to seize the port at Veracruz and prevent the shipment of German arms to the Mexican government. The Mexican government was ousted, just as Wilson wanted. But when the new government proved too independent for Wilson, he began supporting forces under the command of Pancho Villa. When Wilson recognized the Mexican government, the spurned Villa launched raids into the U.S., killing dozens of American civilians. Wilson then ordered Gen. John Pershing to lead an expedition into Mexico to kill or capture Villa, but events in Europe soon trumped all other matters of foreign policy.[xviii]

World War I, 1917-1918      

U.S. military deaths 116,516 (53,402 battle deaths)

U.S. wounded: 204,002

Total serving: 4.73 million

Cost: $20 billion (13.6 percent of GDP in peak year)

Congress declared war on Germany and Austria-Hungary in 1917, after Germany resumed unrestricted submarine warfare and tried to lure Mexico into the war against the United States.

World War II, 1941-1945

U.S. military deaths: 405,399 (291,557 battle deaths)

U.S. wounded: 670,846

Total serving: 16.11 million

Cost: $296 billion, the equivalent of $4.3 trillion today (36 percent of GDP in peak year)

In 1941, Congress declared war on Japan, after Japan’s attack on Pearl Harbor, and then on Germany and Italy, after their declarations of war against the U.S. In 1942, Congress declared war on Bulgaria, Hungary and Romania, after they declared war against the U.S.

Cold War, 1947-1991

Total serving: 35 million[xix]

Cost: $4.65 trillion[xx] (14.2 percent of GDP in peak spending year, 1953)

Berlin Airlift, 1948-1949

U.S. military deaths: 31

Peak U.S. troop level: 32,000[xxi]

Cost: $224 million ($2.2 billion today)[xxii]

Blending the principles of strategic bombing with the efficiency of a Detroit assembly line, Lt. Gen. Curtis LeMay crafted an air campaign unlike any in history. From June 1948 to September 1949, Allied pilots flew 277,000 missions and delivered 2.3 million tons of supplies to Berlin. About 75 percent of those missions were flown by Americans.[xxiii]

Korean War, 1950-1953

U.S. military deaths: 36,574 (33,739 battle deaths)

U.S. wounded: 103,284

Total serving in theater: 1,789,000[xxiv]

Cost: $30 billion (4.2 percent of GDP in peak year)

The war’s economic cost as a percentage of GDP and battle deaths as a percentage of total military deaths underscore why The New York Times called Korea “World War 2.5.”

Vietnam War, 1965-1975

U.S. military deaths: 58,220 (47,434 battle deaths)

U.S. wounded 153,303

Cost: $111 billion (2.3 percent of GDP in peak year)

Total serving in Southeast Asia: 3,403,000[xxv]

Congress authorized President Lyndon Johnson to use “all necessary measures” against North Vietnam in 1964, after U.S. warships came under apparent attack in the Tonkin Gulf. When Johnson asked military leaders what they needed to win, the answer was seven years, 700,000-1,000,000 troops and an unfettered air campaign. Instead, Johnson and President Richard Nixon launched a combined 16 bombing pauses and 72 peace initiatives,[xxvi]thus undercutting battlefield momentum.

Lebanon, 1982-1984

U.S. military deaths: 265[xxvii]
U.S. wounded: 177[xxviii]

Total deployed ashore: 1,800[xxix]

President Ronald Reagan deployed 1,200 Marines to Lebanon as part of a congressionally-authorized multinational peacekeeping force.[xxx]Also deployed were elements of the Sixth Fleet, including USS New Jersey, which unloaded its 16-inch guns during the campaign, and the carriers Independence and John F. Kennedy, which launched airstrikes into the warzone.[xxxi]On October 23, a truck loaded with explosives rammed into the Marine barracks in Beirut, killing 241 Americans.[xxxii]

Grenada, 1983

U.S. military deaths: 19 (18 battle deaths)

U.S. wounded: 116

Total deployed: 5,000[xxxiii]

Reagan deployed U.S. forces to Grenada to rescue U.S. citizens, reverse a Cuban-backed coup and restore order. U.S. forces discovered 800 Cuban advisors and enough weaponry to arm 10,000 troops.[xxxiv]

Persian Gulf, 1987-1988

As the Iran-Iraq War spilled into the Persian Gulf, the two belligerents began attacking commercial shipping. Iranian fighters strafed Kuwaiti tankers. Iran boarded a U.S. civilian ship.[xxxv]An Iraqi warplane attacked USS Stark, killing 37 sailors. To protect Kuwaiti vessels from the maelstrom, the United States began reflagging and escorting Kuwaiti ships.In April 1988, USS Samuel B. Roberts struck an Iranian mine northeast of Qatar. The attack prompted Reagan to order Operation Praying Mantis. “By the end of the operation, U.S. air and surface units had sunk, or severely damaged, half of Iran’s operational fleet,” a Navy report details.[xxxvi]

Panama, 1989-1990

U.S. military deaths: 23

U.S. wounded: 322[xxxvii]

Total deployed: 26,000 troops[xxxviii]

In December 1989, President George H.W. Bush dispatched U.S. troops to protect American citizens, restore Panama’s democratically-elected government and apprehend General Manuel Noriega, who had been involved in drug trafficking, weapons smuggling and a campaign of violence against his political opponents.

Gulf War, 1990-1991

U.S. military deaths: 382 (147 battle deaths)

U.S. wounded: 467

Total serving in theater: 694,550

Cost: $61 billion*[xxxix]

The United States led a large international coalition to defend Saudi Arabia from attack (Desert Shield) and eject Saddam Hussein’s military from Kuwait (Desert Storm). Congress passed an authorization for use of military force (AUMF). There is an asterisk attached to the cost of the war because the war was largely underwritten by international partners.[xl]

Iraqi Kurdistan, 1991

U.S. military deaths: 5

Peak U.S. troop level: 12,316[xli]

When Saddam moved against Kurdish minorities at the end of the first Gulf War, Bush dispatched U.S. forces to mount a massive humanitarian operation in northern Iraq. U.S. forces rescued 400,000 Kurds from starvation.[xlii]The five American deaths listed here came in the initial phase of Operation Provide Comfort and were caused by land mines, weapons misfires and transport accidents.[xliii]The total-serving number is limited to the initial months of Provide Comfort. Follow-on operations continued in Iraqi Kurdistan for years: GAO reported $320.5 million spent on Provide Comfort in 1991. As late as 1996, Congress was still appropriating $143 million for Provide Comfort.[xliv]No-fly zones over northern and southern Iraq were an outgrowth of Provide Comfort. Maintaining these protective umbrellas—and the related sanctions-and-inspections regime—cost $13 billion annually through 2002.[xlv]

Somalia, 1992-1994

U.S. military deaths: 43

Peak U.S. troop level: 28,000

Cost: $2.22 billion (FY1992-FY1995)[xlvi]

Acting in response to UN resolutions, Bush dispatched 28,000 troops to Somalia at the closing hours of his presidency[xlvii]to protect food shipments from tribal warfare and looting. But in 1993, the UN expanded the limited humanitarian mission into an ambitious nation-building effort. When Somali clans ambushed UN peacekeepers, President Bill Clinton sent hundreds of U.S. Army Rangers and Delta Force operators into Mogadishu to apprehend clan leaders, leading to the bloody “Black Hawk Down” episode and triggering the beginning of the end of America’s mercy mission in Somalia.

Haiti, 1994-1996
U.S. military deaths: 5 (all non-hostile)

U.S. troops: 16,253 (plus 11,773 in the “joint-operations area”)[xlviii]
Cost: $2 billion[xlix]
Clinton dispatched troops to Haiti to restore the democratically-elected president to office and stabilize the troubled country. This was nothing new: U.S. forces intervened 16 times in Haiti between 1900 and 1913, before a lengthy occupation from 1915 to 1934.[l]President George W. Bush sent troops into Haiti in 2004, as did President Barack Obama in 2010.

Bosnia, 1995-2004

Total serving: 100,000[li] 

Cost: $14.83 billion (FY1992-FY2004)[lii]

Between 1992 and 1995, the war in Yugoslavia claimed 250,000 people. It wasn’t until a U.S.-led air armada was allowed to take the offensive against Serbian militiamen in late 1995 that Serb strongman Slobodan Milosevic finally came to the peace table. In December 1995, Clinton ordered deployment of 25,000 troops to Bosnia as part of NATO’s follow-on peacekeeping operation.[liii]By the latter half of 2003, the U.S. had sustained “only one hostile fatality,” CRS reports.[liv] The last U.S. troops withdrew in December 2004.[lv]

Kosovo, 1999-Present 

U.S. troops deployed during hostilities: 31,600[lvi]

Cost: $9.56 billion (1999-2004)[lvii]

When Milosevic tried to repeat in Kosovo what he had perpetrated in Bosnia, NATO launched a 78-day air campaign targeting Milosevic’s army and government. Milosevic’s regime was mortally wounded, and 850,000 Kosovar refugees returned home. Two American pilots were killed when their helicopter crashed in Albania. In addition, during the first year of the peacekeeping mission, three U.S. troops died in accidental deaths and 24 U.S. troops were injured.[lviii]About 660 U.S. troops remain in Kosovo, down from 7,000 in 1999.[lix]

Global War on Terrorism/Operation Enduring Freedom (OEF)/Operation Freedom’s Sentinel/Operation Resolute Support, 2001-Present

U.S. military and DoD civilian deaths: 2,355 as of March 2015 (1,846 battle deaths)[lx]

U.S. military wounded: 20,067[lxi]

Americans/friendly foreign nationals killed on September 11, 2001: 2,976

Total serving: 2.5 million+[lxii]

As CRS details, the Bush and Obama administrations have reported “U.S. anti-terror related activities” in Kenya, Ethiopia, Eritrea,Afghanistan, Pakistan, the Philippines, Georgia, Yemen, Iraq, Djibouti and Somalia.[lxiii]In addition, the Defense Department reports that OEF casualties have occurred in “Guantanamo Bay (Cuba), Djibouti, Eritrea, Ethiopia, Jordan, Kenya, Kyrgyzstan, Pakistan, Philippines, Seychelles, Sudan, Tajikistan, Turkey, Uzbekistan and Yemen.”[lxiv]This explains the differing casualty numbers for what might be called “OEF-Global” and “OEF-Afghanistan.” OEF officially gave way to Operation Freedom’s Sentinel and Operation Resolute Support in Afghanistan in late 2014. Congress passed an AUMF in September 2001. According to the 9/11 Commission, “Calling this struggle a war accurately describes the use of American and allied armed forces to find and destroy terrorist groups and their allies in the field.”

Afghanistan War, 2001-Present

U.S. military deaths: 2,215 as of March 2015 (1,832 battle deaths)[lxv]

U.S. military wounded: 20,026[lxvi]

Total serving: 831,576 (as of May 2014)[lxvii]

Cost: $825.7 billion[lxviii]  (0.7 percent of GDP in peak year)

The war in Afghanistan began October 7, 2001. Within weeks, U.S. forces, in conjunction with an indigenous alliance of anti-Taliban militia, toppled the Taliban regime. Then, U.S. troop levels in Afghanistan began to increase: 1,300 in 2001, 10,000 in 2003, 20,000 in 2006 and hitting a wartime high of 100,000 in 2010.[lxix] CBO estimates an additional $1.0 trillion will be appropriated 2015-2024 “for military operations and diplomatic activities in Afghanistan and other possible overseas contingency operations.”[lxx]

Iraq War/Operation Iraqi Freedom/Operation New Dawn, 2003-2011

U.S. military and DoD civilian deaths: 4,491 (3,529 battle deaths)

U.S. wounded 32,244[lxxi]  

Total serving: 1.5 million+ (March 2003-December 2011)

Cost: $820 billion[lxxii](1 percent of GDP in peak year)

Congress authorized military action against Iraq in October 2002, citing “Iraq’s ongoing support for international terrorist groups” and “development of weapons of mass destruction.” Saddam’s army and regime were quickly routed, but Iraq’s postwar war proved costly. And the costs continue to mount.

Operation Inherent Resolve, 2014-Present
U.S. military deaths: 3 (as of March 2015)[lxxiii]
Cost: $8.4 million per day[lxxiv]
The above casualty numbers and economic figures from the Iraq War do not enfold the U.S. military campaign in Iraq and Syria targeting the jihadist army known as ISIS. With military commanders expecting the operation to last more than three years, Iraq promises to dominate the balance of Obama’s presidency, just as it did the previous three administrations. August 2015 will mark 25 years America has been wrestling with Iraq.
