Dictatorship nations are outlaws. Any free nation had the right to invade Nazi Germany and, today, has the right to invade Soviet Russia, Cuba, or any other slave pen. Whether a free nation chooses to do so or not is a matter of its own self-interest, not of respect for the nonexistent 'rights' of gang rulers. It is not a free nation's duty to liberate other nations at the price of self-sacrifice, but a free nation has the right to do it, when and if it so chooses.
Ayn RandIf that's the price of getting together, then I'll be damned if I want to live on the same earth with any human beings! If the rest of them can survive only by destroying us, then why should we wish them to survive? Nothing can make self-immolation proper. Nothing can give them the right to turn men into sacrificial animals. Nothing can make it moral to destroy the best. One can't be punished for being good. One can't be penalized for ability. If that is right, then we'd better start slaughtering one another, because there isn't any right at all in the world!
Ayn RandIf a man wants love he should correct his weaknesses, or his flaws, and he may deserve it. But he cannot expect the unearned, either in love or in money; either in matter or in spirit.
