World War II (1939-1945)

The global impact of World War II reshaped international relations and led to the rise of totalitarian regimes in Europe.

Korean War (1950-1953)

The Korean War which lasted from 1950 to 1953 was a significant conflict that arose from the division of Korea into two separate states following World War II.

In 1945 the Soviet Union and the United States had agreed to divide Korea into two separate zones of occupation with the Soviet Union administering the northern half and the United States administering the southern half.

However the two powers were unable to agree on a unified government for Korea and by 1948 two separate governments had been established โ€“ one in the north led by Kim Il-sung and one in the south led by Syngman Rhee.

Tensions between the two Koreas escalated in 1950 when the North Korean army invaded the South.

The United States which had committed to protecting South Korea in the event of an attack intervened on behalf of the South leading a coalition of United Nations forces that included troops from many other countries.

Vietnam War (1955-1975)

Fought between 1955 and 1975 the Vietnam War was a protracted and divisive conflict between the communist government of North Vietnam and the non-communist government of South Vietnam which was supported by the United States and other anti-communist allies.

The war began as a result of the First Indochina War which ended in 1954 with the Geneva Accords dividing Vietnam into two separate states. However the communist forces in the north refused to accept the division and sought to reunify the country under their rule.

The Vietnam War was marked by a number of significant events including the Tet Offensive in 1968 which saw a coordinated attack by North Vietnamese forces on cities and towns across South Vietnam.

The war ended in 1975 with the fall of Saigon the capital of South Vietnam to the communist forces from the north. The conflict was one of the most controversial in American history with opposition to the war growing throughout the United States during the 1960s and 1970s.

The Vietnam War was also notable for the significant impact it had on the soldiers who fought in it with many suffering from physical and psychological trauma as a result of their experiences.

War on Terror (2001-present)

The ongoing War on Terror which began in 2001 has been characterized by a global campaign against terrorist organizations and individuals who threaten international security and stability. This war was sparked by the 9/11 terror attacks which were carried out by the al-Qaeda terrorist group.

The United States along with its allies launched a military campaign against al-Qaeda and its Taliban hosts in Afghanistan. This campaign known as Operation Enduring Freedom aimed to dismantle al-Qaeda’s infrastructure and remove the Taliban from power.

In addition to the conflict in Afghanistan the War on Terror has also involved military operations in other countries such as Iraq Syria and Yemen. The U.S. military has used a variety of tactics including drone strikes special operations forces and conventional ground troops to target terrorist organizations and their leaders.

Despite these efforts the War on Terror has been a controversial and protracted conflict with no clear end in sight. The conflict has raised questions about the effectiveness of military force in combating terrorism and the balance between national security and individual liberties.
