The Truman Doctrine was a law that helped to give financial assistance to countries struggling after World War II. Thanks to this law, the US would give Greece and Turkey $400 million in aid. The goal would be that these countries would remain free from communism and the reign of the Soviet Union. This doctrine is just the beginning of trying to stop the spread of communism globally.
The Truman Doctrine was just the start of US involvement in global affairs in order to stop the spread of communism. The US passes other laws (like the Marshall Plan) to help European countries. Along with this, the US also gets involved in foreign wars such as the Korean and Vietnam Wars. All of these events were a result of the United States's dedication to stop the spread of communism as laid out in the Truman Doctrine.
Very. thanks to it, America is independent today instead of being part of England. It formed the bill of rights and all the rights Americans have today. So yeah, it is pretty relevant.
