On Nov. 25-26, 1950, the Chinese Army entered the Korean War in earnest with a violent attack against the American and United Nations forces in North Korea. The 300,000-man Chinese offensive caught the U.N. forces off guard, largely because of U.S. Gen. Douglas MacArthur's belief that China would not openly enter the war, and vastly expanded the conflict.

China only entered the war after the US and UN entered the war first... and I mean they were wanting to protect their border... they didn't want a US puppet state right at their neck.... that is way different than bombing and invading people on the other side of the world because you don't want to them to establish an Islamic government
