The Cuban Missile Crisis is an apples vs. oranges issue. The Soviet threat was a clear and present danger to the actual physical territory of the United States. Everyone absolutely agrees with that -- it truly was a direct military threat to the territorial integrity of the nation. There's no question there. The other examples you gave is interventionist nation-building bull**** that has contributed to less security for the United States rather than more.
You absolutely and quite clearly didn't understand a single word I said. Not a single word. I never said that neoconservatives had the exact same individual policies as Marxists -- I said that former Trotskyites adapted their principles to conservatism -- in other words, they adopted the same *tactics* used for a different purpose. Marxists believe in a post-nationalist ideology that is firmly rooted in the need to spread Marxism internationally (how and when is one of the differing characteristics between different types of communism) -- iow, their aim is to spark a revolt of the proletariat globally. When these former Marxists moved from the left to the right, they brought with them that tactic of spreading ideology globally; however, instead of spreading communism, they spread American democracy.I don't know if Trotsky or any Marxist did anything similar, but would be quite surprised if they did.
