What makes you think that Castro would have allowed any sort of "relations" to exist?
Not only that, but how do you justify continued relations with a regime that stole billions of dollars in property from US citizens?
You may think it's OK to legitimize dictatorships via "relations", but I don't.
At last! Finally we have a winner. Someone who knows why we actually have an embargo on Cuba in the first place.
This is the difference between Cuba and China, which the ignoramuses keep scratching their heads about.
A bit of history for the chronologically disadvantaged:
1. The U.S. supported Castro in his toppling of the strongman regime in power at the time. We welcomed Castro as a hero.
2. It was only after consolidating power that he took off the wraps and exposed himself as a murderous communist dictator.
3. We still tried to do business with him until he nationalized the guts of his nonfarm economy, which was owned primarilly by American citizens and American businesses.
4. Despite diplomatic efforts, the sh*t-hook wouldn't compensate the rightful owners for stealing their property.
5. We put an embargo on Cuba in response to the criminal acts of the Cuban regime; which could have been lifted at any time in the last 40 years, by Castro's own act of justice in making amends for his larceny.
It was only incidental that he was a communist. We did not impose the embargo because he was communist. We imposed it because he was a criminal bastard.
6. El Caca has chosen not to do the right thing and as a result has chosen to inflict the embargo on his own people just as Saddam has chosen to impose hardships on his own people.
7. At any given moment both Castro and Saddam have the opportunity to end the embargoes on their countries, in fifteen minutes, at no cost to themselves or their countries' security.
8. They refuse to do so because they are mere psychopaths who would gladly sacrifice their people's welfare for irrational insane egotisms.
To accommodate such scum is beneath us and beneath the aspirations of the people they abuse. Of course, that means it's right up Carter's alley.
Every communist and totalitarian government has confiscated private property, but we deal with them. I guess you think that the policy that results in the property not being recognized after 40 years will get the job done. One definition of insanity is to keep doing the same thing, getting the same results, but hoping for a different result. Your 41 years of lack of results proves the wrongheadness of your approach.
