No, what you're saying is terrible.
Allende was, good or bad (I think more good than bad) a democratically elected president. In contrast, Pinochet was a brutal dictator who came to power through a coup d'etat and enforced his rule via bloodshed, murder and repression of dissidents, students and anyone he didn't like; this included a clandestine plan of cooperation between intelligence agencies of neighboring dictatorships to kidnap and murder dissidents abroad (so that if you were a Chilean dissident living in Argentina, "Plan Condor" ensured you'd be captured and/or murdered there).
There is no possible comparison between Allende and Pinochet.
Being "close allies with Castro" isn't a crime, and to think so reeks of ideological persecution -- the very thing you accuse Cuba of! In democracy, if you don't like a president you wait for your turn to vote a different one. If the president does something grossly illegal, there are legal procedures to remove him from power, like impeachment.
Removal by military force, assassinations and political repression IS NOT AN OPTION IN DEMOCRACY. No matter how allegedly ruinous a government is removal by military force IS NOT AN OPTION. That's not how democracy works! There is no possible crime a democratically elected president can commit that justifies a military coup, the banning of all political parties and clandestine torture centers. Nothing.
At this point you might tell me that you don't think democracy is above all possible problems, that some emergencies may justify suspending the rule of law... but in that case, your criticisms of Cuba and Fidel ring very hollow. You'd be on very shaky ground.
You disgust me. We have nothing in common. I'm stopping this discussion now.
