Why are we constantly at war?

We are not innocent victims who are defending themselves against evil. We brought most of this on ourselves because of our own history of meddling in the affairs of others.
 
They didn't attack us on 9/11 because of our freedom. They attacked us because we set up bases in Saudi Arabia during the first Gulf War and then never left. Then after 9/11 Bush and his cronies thought it would be a great idea to invade and make Iraq a client state, so we could close most of our bases in Saudi Arabia and replace them with a bunch of fortified bases in Iraq. How's that working out so far? 

We do not have to be the world's policeman. We don't have to protect oil that goes mostly to Europe and Asia. We don't have to support 'everything' Israel does. We don't have to go to war against Iran to stop them from getting nukes. We don't have to over-dramatize everything that happens in the world in order to justify more military misadventures. We don't have to take up arms and go to war every time the chicken hawks say we should. We do need to be aware of how we are being manipulated by our leaders who do the bidding of the multinational corporations and rich folks, including foreign nationals, who finance their campaigns.
