This is the most idiotic perception that most people commonly incur because they have never lived under a totalitarian Stalinist regime.
Millions of European, Canadians and Latin Americans have been traveling to Cuba. Europeans, Japanese, Canadians and Latin Americans (150 nations around the world) hungry for business went to Cuba and were defrauded by Castro to the tune of more than 20 billion dollars not including the 25 billions Cuba owes to the Russians. Year after year the Soviet Union poured into Cubas economic black hole 5 billion dollars in subsidies and almost as much in military help.
All that infusion of people and money did not result in an iota of freedom, democracy or economic development to Cuba and its people. Their approach of helping Castro through commerce and investments was the one that failed instead of the U.S. embargo. After all, these nations also deal with dollars and they produce and provide Castro with anything we produce.
To affirm that the result of the interaction with the American tourists and businesses would be in anyway different to those obtained by the other 150 nations that have been dealing for 43 years with Castro, is to believe that freedom, democracy, and business acumen is a virus that can only be transmitted by contact with Americans.
