Yes, the cost of national defense is an irksome thing. It would be nice if we didn't have enemies in this world, foreign and domestic.
I have no objection spending billions on national defense and security. The line in the sand appears when it is spent on Teddy's education plan, housing and "urban" development & heating assistance programs that goes in the pockets of poverty pimps, and highway boondoggles that states should be paying for themselves. In fact states should be stepping up and taking care of all domestic programs, and SS/Medicaid/Medicare should be gradually phased out.
