US Wars Span 250 Years, Causing Millions of Deaths and Trillions in Costs

According to the International Desk of Webangah News Agency, the United States has engaged in numerous wars over its 250-year existence, driven by nation-building efforts, domestic development, global dominance aspirations, and the ultimate goal of asserting control over regions like the Middle East and Africa.

Since its founding in 1776, the U.S. has undertaken around 400 military interventions. The pace of these conflicts has markedly increased since the end of the Cold War, incurring substantial human and economic tolls worldwide. The estimated cost of post-9/11 wars alone, accounting for injured veterans and loan interest, approaches $6.4 trillion, resulting in hundreds of thousands of deaths and millions of displaced persons.

While the U.S. Constitution vests Congress with the authority to declare war and grants the President the role of Commander-in-Chief, a distinction exists between a formal declaration of war and the authorization of military force, the latter allowing the President to employ power against specific states or organizations without a formal declaration.

In the 19th century, U.S. wars were often justified by notions of sovereignty, nation-building, and territorial expansion, aiming to secure borders, acquire fertile lands, and extend commercial influence, leading to conflicts with indigenous populations and neighboring powers. American policymakers at the time viewed the acquisition of new territories and the spread of the American model as essential for advancing civilization and liberty.

During its transition to global power status after independence, the U.S. initiated conflicts with justifications such as opening new markets, securing maritime routes, and competing with European powers.

The containment of communism also served as a pretext for U.S. military actions. However, following the collapse of the Soviet Union, justifications shifted to maintaining regional stability, securing oil resources, combating terrorism, and preventing the proliferation of weapons of mass destruction.

The article highlights that throughout its 250-year history, the U.S. has instigated hundreds of wars, leaving behind millions of dead and displaced. It contends that claims of civilization, freedom, democracy, and human rights, often used to justify American military actions, are mere pretexts, with the underlying motive being the pursuit of self-interest and the exploitation of other nations. Al Jazeera has reportedly covered some of the most significant conflicts involving the U.S.

19th Century Wars and Early Expansion

Conflicts of this era reflected a transition from continental expansion and North American dominance to overseas expansion and the extension of influence beyond oceans and distant lands.

A: The Mexican-American War (1846-1848) resulted in 1,733 U.S. military deaths and the participation of 78,718 soldiers. Its most significant outcome was the acquisition of vast territories, including California, New Mexico, and Texas, completing U.S. territorial expansion to the Pacific Ocean.

B: The Spanish-American War (1898) aimed to annex Puerto Rico, Guam, and the Philippines, and gain effective control over Cuba. This war was instrumental in elevating the U.S. to the status of a major global imperial power, initiating imperial interventions and regime changes abroad, and seeking to open commercial markets and secure naval bases and passages.

C: The Philippine-American War (1899-1902) was fought to consolidate direct colonial control over the Philippines until the mid-20th century. Establishing a network of military bases to protect trade routes in the Pacific and extend U.S. strategic influence into Asia were other objectives. This conflict is described as a brutal example of counterinsurgency warfare and the suppression of national liberation movements by the U.S.

World Wars and the Cold War

While not initiated by the U.S., World War I and World War II significantly contributed to advancing American international interests and reshaping global power balances in its favor. Following World War II, the U.S. emerged as the undisputed global power. The end of the Cold War and the collapse of the Soviet Union marked the official commencement of a unipolar world order dominated by the U.S.

The Korean War (1950-1953) concluded with an armistice, dividing the Korean Peninsula and reshaping regional alliances. This conflict was undertaken without a formal declaration of war to circumvent the limitations of a full declaration and widespread direct confrontation.

The Vietnam War (1965-1973) primarily resulted in the U.S. becoming entangled in a protracted war of attrition, ending with the withdrawal of American forces in 1973. Key consequences included a decline in domestic confidence within the U.S. and a erosion of the legitimacy of foreign military intervention and political institutions.

The Vietnam War is characterized as a long and costly war of attrition, conducted without a formal declaration and relying on flexible executive authorizations to manage operations.

Post-Cold War Conflicts

These conflicts, commencing after 1991, occurred within a unipolar international landscape and featured protracted durations, complex coalitions, and hybrid warfare tactics, signaling significant shifts in U.S. power projection. They represent a transition from a unipolar logic based on technological superiority to entanglement in wars of attrition, limited strikes, and intricate regional alliances, many of which were framed as part of the “War on Terror” following the September 11th attacks.

A: The First Gulf War (1990-1991) in Iraq aimed to expel Iraqi forces from Kuwait and degrade the military capabilities that the U.S. had supplied to Saddam Hussein’s regime during the Iran-Iraq War.

B: The Kosovo War (1999) in the former Yugoslavia (Serbia) was notable for its disregard for United Nations Security Council resolutions and its reliance on intensive aerial bombardment without the use of ground troops.

C: The invasion of Afghanistan (2001-2021) devolved into a long-term war of attrition for the U.S., concluding with its complete withdrawal and the Taliban’s return to power in 2021. This war imposed a colossal economic burden and resulted in significant human casualties in both the U.S. and Afghanistan.

Key characteristics of this longest U.S. war of attrition included international mobilization against regional and unconventional adversaries and extensive use of precision technology, such as drones, to minimize direct engagement.

D: The invasion of Iraq (2003-2011) led to the overthrow of Saddam Hussein’s regime and a prolonged, attritional occupation until the U.S. withdrawal in 2011. The U.S. spent over a trillion dollars on operations in Iraq and was responsible for the deaths of over one million Iraqi citizens.

E: The war against ISIS in Syria and Iraq (2014-2019) was waged against the terrorist group ISIS. Current U.S. President Donald Trump has stated that previous U.S. administrations were primarily responsible for the group’s formation. A key U.S. approach in this conflict involved intensive airstrikes to secure interests without extensive ground occupation, relying on limited long-range strikes and drones to prevent protracted engagement.

F: The war with Iran in 2026 has imposed severe financial and economic costs on the global economy. Notable features of this conflict include the deployment of advanced technologies such as drones to mitigate the technological and quantitative gap between the warring parties, and the confluence of stated justifications for military action, including the nuclear program, regional security, and regime change in Iran.
