There is a direct connection between the massive level of U.S. military spending and belt-tightening austerity at home: most federal discretionary spending goes for war. Aren't there other, better things that Americans could be doing with their money?
We've designed an entire religion around the Pentagon's untouchability. When the U.S. government nearly shut down, both parties agreed to exempt the Pentagon from a spending freeze and actually added $5 billion to its budget.
Frankly, I would prefer that crowds in the Muslim world came together in angry, peaceful protest not when Terry Jones issues his video plea for attention, but when the U.S. president submits the annual budget proposal for military spending.
