You can't beat a well orgaized and financed communist takeover by sending nicely worded diplomatic notes.
You have to choke their windpipes before they drive their dagger into your heart.
Oh for a Cuban Franco!
There were Cuban Franco's. They were stabbed in the back and led to the slaughter by JFK. Castro held his troops back from attacking during the Bay of Pigs because we had a carrier right off the coast to support the revolt. When it became obvious that we were not going to launch any planes he moved his armor in for the slaughter. I remember reading a first hand account of a crewman on the bridge who saw the Admiral BEG "Please, Mr. President, just one plane." The Admiral broke down in tears.
Despite no air cover, the Cubans put up a fierce resistance. With air cover, most military analysts say that Castro would have hid in the hills and 40 plus years of suffering could have been avoided.
Oops. Forget to add "Well put". If only people would open their damn eyes and compare and contrast Chile with Argentina or Spain with Yugoslavia.
