2. Our "support" of Batista was simply our recognition of the current legitimate government of Cuba - had Castro not expropriated large amounts of property owned by U.S. citizens and gotten in bed with the Soviet Union, we'd have probably recognized him as well.
3. The "Clinton doctrine"? You're joking, right? How long have you lurked here? Does the name Riady ring a bell? Huang? Mena, Arkansas?
I doubt if that opinion will get you banned, but it might get you flamed a bit. Underlying it is the assumption that if the guys we supported were bad guys, the other guys were good guys, and that is demonstrably untrue. In the case of Khomeini, the bad guy - the Pahlavi Shah - we supported was displaced by a worse guy who would have hated us anyway no matter what we did before him. Sorry, but foreign policy just works that way - we bombed Milosevic and got the KLA; if we'd bombed the KLA we'd have Milosevic, and your complaint would be made either way. If we hadn't bombed anybody we'd be culpable for letting "ethnic cleansing" continue and your complaint would still be made.
Where we've backed stinkers, it was generally because the other guy was worse, or at least we thought so at the time. Hindsight is 20/20; it's a pity you can't conduct foreign policy on that basis.
Excuse me?
