-
Which country controlled Vietnam as a colony before World War II?
France
France colonized Vietnam as part of French Indochina, which also included Laos and Cambodia. French colonial rule began in the mid-19th century and lasted until France's decisive military defeat at Dien Bien Phu in 1954. The legacy of colonial exploitation fueled Vietnamese nationalism and the independence movement led by Ho Chi Minh.

The 1954 Geneva Accords temporarily divided Vietnam at which latitude?
The 17th parallel
The Geneva Accords of 1954, signed after France's defeat at Dien Bien Phu, divided Vietnam at the 17th parallel into a communist North and non-communist South. The division was intended to be temporary, with nationwide elections planned for 1956, but those elections were never held due to fears that Ho Chi Minh would win.
Fun Fact: The 38th parallel, the other famous Cold War dividing line, separates North and South Korea.

What was the Gulf of Tonkin Resolution?
A congressional authorization giving the president broad war powers in Southeast Asia
Passed by Congress on August 7, 1964, the Gulf of Tonkin Resolution authorized President Lyndon B. Johnson to take "all necessary measures" to repel attacks against U.S. forces and prevent further aggression in Southeast Asia. It effectively gave the president a blank check to escalate the war without a formal declaration of war. The resolution was based on reported attacks on the USS Maddox, the second of which is now widely considered not to have occurred.
-
What was the Ho Chi Minh Trail?
A network of supply routes running through Laos and Cambodia to South Vietnam
The Ho Chi Minh Trail was an elaborate network of paths, roads, and trails running from North Vietnam through Laos and Cambodia into South Vietnam. It served as the primary supply route for North Vietnamese troops and the Viet Cong. Despite massive U.S. bombing campaigns, the trail was never successfully cut off and was vital to North Vietnam's war effort.
-
The Tet Offensive, launched on January 30, 1968, coincided with which event?
The Vietnamese New Year (Lunar New Year)
The Tet Offensive was a coordinated series of surprise attacks launched by North Vietnamese and Viet Cong forces during the Tet holiday, the Vietnamese Lunar New Year. Although it was a military defeat for the North — they failed to hold any major targets — it was a strategic turning point because it shattered American public confidence that the war was being won.
Fun Fact: During the offensive, a squad of Viet Cong fighters briefly breached the U.S. Embassy compound in Saigon, an event broadcast on American television that shocked viewers at home.

Over the course of the campaign, U.S. aircraft flew more than 300,000 sorties and dropped roughly 864,000 tons of bombs.

South Vietnam

Only one officer, Lieutenant William Calley, was convicted, and he served just three and a half years of house arrest.

What was "Vietnamization," the policy introduced by the Nixon administration?
A strategy to gradually transfer combat responsibility to South Vietnamese forces while withdrawing U.S. troops

That the U.S. government had systematically lied to the public about the war's progress and scope
The Pentagon Papers were a top-secret Department of Defense study of U.S. political and military involvement in Vietnam from 1945 to 1967. Leaked to the New York Times by military analyst Daniel Ellsberg, they revealed that multiple administrations had misled the public about the war's scope and prospects. The Supreme Court ruled in favor of the newspapers' right to publish them in New York Times Co. v. United States (1971).

Which country did the U.S. secretly bomb beginning in 1969 in an effort to destroy North Vietnamese sanctuaries?
Cambodia
Beginning in March 1969, the Nixon administration secretly bombed Cambodia in Operation Menu, targeting North Vietnamese and Viet Cong base camps along the border. The bombing was kept hidden from Congress and the American public for over a year. It was later expanded and, combined with a 1970 ground incursion, destabilized Cambodia and contributed to the rise of the Khmer Rouge.
Fun Fact: The U.S. also dropped more than two million tons of bombs on Laos between 1964 and 1973, making it the most heavily bombed country per capita in history.

He was proven right — fighting continued until 1975.

Saigon fell on April 30, 1975, when North Vietnamese tanks rolled into the city and crashed through the gates of the Presidential Palace.

Johnson announced he would not seek re-election just one month later.
