Demilitarized Zone  -  A buffer zone between North and South Korea created under the terms of the armistice signed on July 27, 1953 which ended the war. Though the zone was supposed to be free of both troops and weapons, in practice it is heavily militarized, with over 1 million North and South Korean troops facing off.

Open Door  -  An 1899-1900 foreign policy of the US in reference to China, under which all countries would have equal trade privileges in China.

Russo-Japanese War  -  1904-1905 conflict between Imperial Russia and Japan primarily over Manchuria. The Japanese routed and embarrassed the Russians and defeated their fleet. At the Battle of Mukden, which the Japanese won, more soldiers (624,000) were involved than in any battle before or since. The Treaty of Portsmouth, mediated by US President Teddy Roosevelt, ended the war, and gave Japan a protectorate in nominally-independent Korea.
Sino-Japanese War  -  1895 war in which the Japanese soundly defeated China, and began looking to expand into China's traditional sphere of influence.
Wake Island  -  Island in the middle of the Pacific where MacArthur and Truman met on October 15, 1950. Truman wanted to remind MacArthur of the importance of keeping the Korean conflict limited, and of the importance of ending the war as soon as possible. MacArthur thought Truman wanted to appear in pictures with him for political reasons, so he wore old clothes, didn't put on a tie, and refused to salute his President lest a photographer take a picture. The Wake Island meeting increased MacArthur's hatred for Truman. The meeting also suggested to the Chinese that the Americans were preparing a major operation, and perhaps attempting to reopen the Chinese Civil War. The meeting may have therefore inadvertently helped lead to Chinese involvement in the war.
