No, no, don't get me wrong. There is a military industry in this country, and needs to be. But not because we are necessarily a waring nation, or as many liberals like to label it imperialist, but rather because as the strongest military on earth, we have responsibilities, that as a moral nation in that position must not be ignored, or minimized. The vacuum created in the event that the US scales back in its protection of weaker nations is not a world that I'd want to see.
I also get frustrated with the way our aid, and protection is perceived as well, but if you just say 'that's it, we're out!' Who will fill that vacuum? China? Russia?....More people would die, and more people would be subject to dictatorial rule in the world. Plus, we would be more vulnerable.
