The Romans would disagree with you, and so would the Greeks, Turks, Russians and the old English. In fact not too long ago the Americans would have disagreed too. War is hell, winning ends the war and the hell, PCism only prolongs both, for everyone.
Rome empire is dead and buried, so to is Ancient greece, and the Turkish, the British and Russian empires as well. And once upon a time Our forefathers were given the choice between an American Empire and an empire of Ideas, chose to be what you would call PC and I would call a new morality.
We don't need to slaughter all that are against us, even though we have that ability.
We don't need to kill innocents by the millions to kill hundreds of our enemies.
Our strength is not measured in our ability to kill but in our ability not to. Any brute can kill and brutal empires run by the sword and the gun have always shown that they cannot withstand the humblest of men.
Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.
Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this.
But, in a larger sense, we can not dedicate -- we can not consecrate -- we can not hallow -- this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us -- that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion -- that we here highly resolve that these dead shall not have died in vain -- that this nation, under God, shall have a new birth of freedom -- and that government of the people, by the people, for the people, shall not perish from the earth.
You would do well to remember that it is those ideas that made this country great and strong that are the only thing that are really worth fighting for and worth protecting.
Pretty eloquent "preamble". Almost worthy of the sentiments that followed it.
