You have neither the power nor the right to "flood Cuba with capitalism".
Most people have lived for two or three generations in a house that once belonged to richer Cubans who came to the US.
Telephone service is about 1/10 what they charge here, or free.
Education and medical care are free to all.
When Cuba had something like capitalism, it also had racism. No one wants that to return
"Flooding Cuba with Capitalism" would end all that. It would go over like a lead balloon.
Remember, the Cubans who LIKE capitalism (and racism) are mostly all here in the US.
Simply ending the embargo and letting things take their course without US meddling would be the best for Cuba as well as the US.

I have no idea what you mean by "Rocky IV". Do you get your ideas on political theory from old Stallone films?
If that would work, we'd just hire Rambo to win the war in Iraq and then we could send him on to Afghanistan. He could win each war in 90 minutes, just like he freed all those MIA's.
