Could ending all of our wars, getting out of all muslim lands & raising taxes slightly save the day?

These wars cost us several billion dollars a day, not to mention all the other expenses that go with maintaining an 800 billion borrowed dollar a year military. We pay three or four billion a day in interest on our debts. I see a window of opportunity here to radically change the algebra of this situation without sticking it to the less favored. A lot of folks sacrificed their lives and limbs over the last decade...if we ask the most favored among us to sacrifice a few bucks for a decade so we can pull out of this dive, what's the harm? How about some long and thoughtful answers. I promise I'll read them.
