The war officially ended with the signing of the Treaty of Paris in 1783, when Great Britain officially recognized the independence of the 13 colonies. american. These colonies were declared independent states, and the US eventually expanded to 50 states.

First World War, also known as The Great War, was one of the largest global conflicts in history. War broke out in Europe in 1914, but the US did not officially join the war until 1917, after the presidencyWoodrow Wilsonurged Congress to declare war on Germany. This was partly due to Germany's breach of its agreement to end its submarine warfare against the US in the Mediterranean and North Atlantic. Germany had also tried to persuade Mexico to join them in solidarity against the United States.

okorean war, also known as the Korean conflict, began when the army of North Korea, a communist country, invaded South Korea. North Korea's goal was to conquer South Korea and unite the two nations under a common communist regime. The Soviet Union or USSR also played an important role in the conflict, providing medical services, pilots, and aircraft in support of the North Korean and Chinese forces. This contributed to increasing tensions between the former allies of the US and the USSR.
The United States led United Nations (UN) efforts to assist South Korea in its fight against North Korea. The UN forces included troops from a dozen countries. China provided aid to North Korea. After the conflict ended in a stalemate, the Korean Demilitarized Zone was created to establish a buffer zone between North and South Korea.
The Vietnam War was fought between forces representing communist countries.Southeast Asia, led by North Vietnam, against South Vietnam and other countries in the region that are not under communist rule. The United States was involved from the beginning, initially providing ground training for South Vietnamese forces.
The United States became more directly involved through special forces, ground forces, and air strikes. The United States used Agent Orange, a toxic herbicide and defoliant chemical, against the North Vietnamese forces. The United States completed a long troop withdrawal in 1973, and the war officially ended in 1975. North Vietnam prevailed. After the end of the Vietnam War, Laos, Cambodia, and South Vietnam became communist states.
nogulf war, dubbed Operation Desert Storm, the US-led coalition forces authorized by the United Nations. This coalition included troops from 34 nations that worked together to achieve the goal of liberating Kuwait from Iraq. In the summer of 1990, Iraq managed to take over and occupy Kuwait in a few hours. After the UN embargo and sanctions failed, the next step was military force. The coalition emerged victorious in its effort, which involved air and ground forces. Kuwait was liberated despite the fact that Saddam Hussein's regime remained in power in Iraq.
Although the 21st century is many decades ahead, the US has already been involved in two major wars.
Dubbed Operation Enduring Freedom, thewar in afghanistanbegan shortly after the September 11, 2001 attacks on the World Trade Center in New York and the Pentagon in Washington, DC in 2001. The purpose of this military action was to remove al-Qaeda and Taliban forces from power in Afghanistan . The Taliban quickly withdrew and collapsed, but Taliban leader Osama bin Laden escaped. A transitional government came to power, reconstruction began, and major hostilities ceased in 2003. The armed forces remained to provide aid and support while progress was made.
However, widespread uprisings remained in the country. Osama bin Laden resurfaced and was eventually assassinated by US special forces in 2011. Troop withdrawal was announced soon after, but ten years later instability persisted, as did a significant US military presence. The US government planned to withdraw all US forces and allied troops by August 31, 2021. However, the Taliban and allied militant groups launched a broad offensive in the summer of 2021, capturing Kabul and with he the country on August 15, 2021. The last US military aircraft left Afghanistan on August 30, officially ending the US military presence in the country.
After the terrorist attacks of September 11, the USled coalition forces against Iraqin 2003. This military action was initially calledOperation Iraqi Freedom, renamed Operation New Dawn a year before the end of the conflict. After diplomatic attempts with Iraqi dictator Saddam Hussein proved ineffective, US President George W. Bush declared war on Iraq, arguing that Iraq was part of a "axes of evil' which also involved Iran and North Korea in the process of building weapons of mass destruction. The Bush administration launched massive airstrikes in Iraq and Hussein went into hiding shortly after the first attack.
The US-led coalition successfully overthrew the regime of Saddam Hussein, who was captured, tried and eventually sentenced to death. However, the conflict continued and the insurgents opposed the formation of a new government in Iraq. In 2007, the United States began to reduce its military. By the end of 2011, all US troops had left the country. This officially ended the war in 2011.
