February-7th-The U.S. gives monetary help of 75 million U.S. dollars to help the South Koreans. 1952- Turkey and Greece (the two countries that received help from the Truman Doctrine) join NATO, which guarantees their protection. 1953-February-3rd-The U.S. pulls out the 7th fleet so it could no longer help defend against nationalist attacks on the Chinese mainland.
