What was the Cairo Conference?
a discussion among Western leaders about how to contain communism
a mid-WWII discussion of the Allies' position on Japan and Asia

This meant that the Allied leaders decreed that Korea "shall be free" after Japan's defeat.

Yuri Andropov
Nikita Kruschev

Technically, the pro-Western forces in South Korea were under the command of which nation?
USA
United Kingdon
South Korea
they were controlled by the UN
Technically, what happened in Korea was not a war but a "UN police action." Which is not a convincing argument when your country is full of soldiers, tanks, and artillery arrays.

The UN resolution to send troops to South Korea was called what?
the Truman Resolution
the Marshall Resolution
the Seoul Resolution
Resolution 83
It's not the most stirring name! In contrast, U.S. military actions have names like "Desert Storm" -- created by Pentagon think tanks in order to appeal to the public.

Why didn't the Soviet Union's UN delegates vote against Resolution 83?
the Soviets were confident North Korea would win
the Soviet Union was boycotting the UN at the time
The boycott was based on the fact that the UN did not acknowledge the new communist government of China. In solidarity, the USSR boycotted the United Nations -- and therefore did not vote on Resolution 83. It seems likely that the United States would have found a way to go to war in defense of South Korea anyway, but it didn't have to.
the Soviets didn't want to provoke the US
they did vote against it, but were overruled

Which of these countries was not part of the UN "police action"?
Colombia
Italy
Sixteen countries formed the UN coalition that sent troops to South Korea. Some of its constituents might surprise people today, who don't think of countries like Colombia as natural US allies. Nor is Thailand thought of as a military power -- but it sent approximately 1,300 soldiers to the effort.
South Africa
Thailand

What percentage of soldiers in the UN force were neither American nor South Korean?
5 percent
When you look at the troop numbers, it's clear that the UN police action was a thinly-veiled American mission.

The next-nearest number were 14,000 from Great Britain.
12 percent

de-mobilized and went home
stayed as a limited defense force in Seoul
kept up a force at the 38th Parallel
advanced into North Korea, all the way up to the Chinese border
MacArthur felt certain that China would not act if UN forces attempted to take the North and unify Korea under capitalist rule. This isn't to say that MacArthur acted solely on his own initiative: a secret memo from the defense secretary gave him the go-ahead to cross into the North.

How did China respond when MacArthur's forces entered North Korea?
censured the US openly in a UN session
sent troops to defend North Korea

Which of these was a major issue preventing a peace treaty?
both sides' desire to rule the whole country
northern POWs refusing to be repatriated

an issue of financial reparations
the continued influence of China on the North

What is/was No Gun Ri?
a suggested boundary to replace the 38th Parallel
a war memorial
a massacre of civilians
As many as 400 Korean civilians were killed by an air and ground attack near the village of No Gun Ri. The Associated Press broke the story in 1999 ("broke" meaning to the wider world; the incident was well known inside Korea). In a controversial move, U.S. troops were ordered at the time to fire on civilian refugees, because the KPA was disguising soldiers as refugees in order to get them close enough to attack.
