Greece and Turkey were responsible for the Manhattan Project
"In the 1960's Greece had many economical and industrial problems which caused for others like the United States to provide aid. Along with Greece, Turkey was in the same standing and were both on the edge of being invaded by greater powers like Europe. That was all made possible by the Marshall Plan which the U.S. provided for the Soviet Union along with Greece. Yet another aid that could be taken into account was the Manhattan Project which caused an intervention in Vietnam."
