Americans have been staging wars of liberation in Bosnia, Kosovo, Afghanistan, and now Iraq. We have armies all over the world. We were supposed to be out of Bosnia in a year. That was seven years ago, We are still in Kosovo too. We turned NATO into an offensive weapon, rather than a defensive alliance with the Kosovo attack. If the UN says no, we will blow it off and do it anyway, just like Hitler did when the League of Nations said he could not annex Austria or the Sudatenland.
I am merely conjecturing that what appears as a good cause, stopping the spread of WMD to terrorist groups is actually the second step in a planed trip for world domination. The foothold in Iraq is merely a stepping stone in the "modern domino" theory. Remember it is a war that has no end. The similarities of America 1900 and 1930's Germany is stronger than the similarities of Saddam to Adolph.
Hitler convinced his people that the war in Poland was self defense. Remember the announcement of the invasion started "At dawn today we began returning fire..."
