25th June – North Korea invades South Korea. North Korean propaganda claimed that the invasion was in reaction to a South Korean attack, however this was unfounded. When Truman heard of the invasion he was outraged, remarking "By God, I'm going to let them have it!" The US viewed the attack as a test to see how the West would react to a Communist invasion. Inaction would only serve to repeat the mistakes of Appeasement of the late 1930s. Truman made sure that the US intervention in the war was first ratified by the United Nations. This gave it a legitimate basis. However, this only occurred because the USSR, who had the power to veto such intervention in the Security Council, were absent in protest over the failure to admit Communist China into the organisation.
