Korea was divided into two parts, North and South. North was friendly with the USSR and was communist. The South was friendly with the US and was a democratic nation.
I am communist and this is my friend, USSR
Yes, the Korean War. One of my favorites. I, Captain Communist, hope the USSR wins! Of course.
This is my friend, the US
North Korea invaded South Korea to try and take over the south.
We want the whole peninsula!
No we want it!
The United Nations decided to aid South Korea. Truman sent MacArthur and his troops to South Korea. They landed at Inchon. As a result, the Chinese entered the war with North Korea and pushed MacArthur's army back past the 38th parallel (Boundary between North and South Korea).
We, China, are here to help you!
My UN friends, MacArthur, and I are here to aid you!
Truman was insistent on getting A-bombs to bomb China but Truman did not want to, as it would lead to more conflict and possibly the world being destroyed.
We need A-bombs to bomb Chinese supply lines!
Bombing China is not the right solution!
The war stalled for two years with neither side doing anything significant against each other.
This war is so boring. No one has done anything for two years!
MacArthur sent an angry letter to Truman since MacArthur wanted to be aggressive in the war. Truman responded by firing MacArthur.
