Answer: Four Point Aid
Step-by-step explanation:
The North Atlantic Treaty Organization (NATO) is a military alliance that was formed to counteract the threat of the Soviet Union and other Communist countries.
The Marshall Plan was enacted to help Europe recover such that discontent in their countries would be quelled and they wouldn't fall to Communism.
The Berlin Airlift was as a result of the Soviet Union blockading West Berlin so this was also a response to Communist threats.
The Four Points Plan however, was enacted to help underdeveloped countries and was not done as a response to a communist threat.
