US taxes are too low, and spending is too high.
Raise taxes, reduce the amount wasted on the military, and the problem is gone.
Does that prevent future presidents from embarking on foolish military adventures to prop up their poll numbers? Maybe, would that be bad?
There is a lot of room between what the US collects in taxes and what other nations collect, especially in the higher brackets, it's quite possible to raise taxes on the higher brackets, save social security and fund National health, and give most people a tax cut.

And it's a plan that would would get a politician more votes than it would lose him.
