The events happened on 25th June are :



1950 : Korean War begun : On this day North Korea, with the tacit approval of the Soviet Union, unleashed a carefully planned attack southward across the 38th parallel. The United Nations Security Council (minus the Soviet delegate, absent in protest against the UN's failure to admit the People's Republic of China) met in an emergency session and passed a resolution calling for the assistance of all UN members in halting the North Korean invasion. On June 27 U.S. President Harry S. Truman, without asking Congress to declare war, ordered U.S. forces to come to the assistance of South Korea as part of the UN “police action” that became the Korean War.



1943 : The Smith-Connally Anti-Strike Act was enacted by the U.S. Congress, giving the president power to seize and operate privately owned war plants when a strike or threat of a strike interferes with war production.
