Theirs is the banner in my hand. And I wish I had the power to tell them that the despair of their hearts was not to be final, and their night was not without hope. For the battle they lost can never be lost. For that which they died to save can never perish. Through all the darkness, through all the shame of which men are capable, the spirit of man will remain alive on this earth. It may sleep, but it will awaken. It may wear chains, but it will break through. And man will go on. Man, not men. ~Equality 7-2521 (as Prometheus), pgs 103-104
Ayn RandDictatorship 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.
