2- The Truman Doctrine was a policy which implied that America had an obligation to assist nations subject to communist aggression--after Congressional funding it was known as the 'Containment Policy'

3- to stabilize the European economy and strengthen nations vulnerable to communist aggression Congress passed The European Recovery Act to the tune of 12 billion dollars, later referred to as The Marshall Plan
