Please site your source on that graphic. It seems to be missing social programs in toto, unless that has been lumped into "HR." I'd like to explore its rationale a bit more.

Yes there are off-book expenditures in the defense budget. But there are also off-book expenditures in all of the other divisions of the budget as well, pretty substantial amounts in the other divisions related to pensions and medicaid actually. The point of the CBO data (which is run by Congress, which is run by Democrats FYI) is to compare apples to apples by looking at current year expenditures for the current year and exclude off-book expenditures.

The point of me posting that graphic is that, like every other issue we face, the solution isn't simple and there is no silver bullet. For someone on the left to say "the problem is the defense budget, just cut it!" is about as ridiculous as someone on the right saying the same thing about any of the other budgets. The truth is that the only way we are ever going to see balanced budgets is by increasing the tax rate substantially and making drastic spending cuts across the board effecting all budgets.
