USA moving off wars and oil would actually increase the cost at home in the short term which people just aren't ready to let happen

this is the ill effect of a globalised economy that somebody has to work.today's globalised system makes industrailized nations live easy and slave other countries and they don't feel like getting out of that easy lifestyle

I was just wondering how would not going to war increase the cost of the defense budget?
