I am somewhat familiar with how the U.S. federal government spends its money, but it is still instructive to see it broken down occasionally. Once social security, medicare, and interest are taken care of, the discretionary spending that is left is less than a third of the total. Of that, more than half is military. Veterans’ benefits make up another sizable chunk, nuclear weapons are partially funded under the energy budget, and it is not clear (to me at least) where intelligence and homeland security funding fall, so the real total for military and security is even larger than it appears.
