When I joined I took an oath. In that oath I swore to protect the Constitution of the United States. I didn't swear to build democracies in countries on the other side of the world under the guise of "national security." I didn't join the military to be part of an Orwellian ("1984") war machine that is in an obligatory war against whoever the state deems the enemy to be so that the populace can be controlled and riled up in a pro-nationalistic frenzy to support any new and oppressive law that will be the key to destroying the enemy. Example given – the Patriot Act. So aptly named, and totally against all that the constitution stands for. President Bush used the reactionary nature of our society to bring our country together and to infuse into the national psyche a need to give up their little-used rights in the hope to make our nation a little safer. The same scare tactics he used to win elections. He drones on and on about how America and the world would be a less safe place if we weren't killing Iraqis, and that we'd have to fight the terrorists at home if we weren't abroad. In our modern day emotive society this strategy (or strategery?) works, or had worked, up until last month's elections.
My point in this; to show that America was never nationalistic. If anything they were Statalistic (giving their allegiance to the state of their residence).
