What are 2 things that greatly the american economy after the war?
the huge buildup in u. s military.
the beginning of the korean conflict
the creation of the gi bill.
the marshall plan for nations.

The two things that greatly helped the American Economy after World War II were the creation of the GI Bill, and the Marshall Plan for helping nations. After WWII the Truman administration passed the Servicemen's Readjustment Act, also known as the GI Bill, by which veterans were provided with low-cost loans to buy a house, or start a business. They also had the opportunity of free college education. The Marshall Plan helped U.S. economy because the European nations and Japan, in return bought machinery from the U.S.

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
