That analysis is deliberately manipulated to exaggerate the percentage of government spending that goes to the military. First, they throw out Social Security and Medicare. Their rationale is that these are ostensibly paid for with a payroll taxes rather than income taxes, but that's not important. The bottom line is that all of it is money that's being spent and has to be paid for with taxes.
Second, they attribute 80% of the interest on the debt to past military spending. The rationale is that if we hadn't had a military, we wouldn't have had 80% of the debt. But the same is true of anything else the government spends money on. If we hadn't spent anything on welfare programs, we'd have less debt, too. The reasonable thing to do is attribute the debt to programs according to the proportion of government spending they took up during the years in which the debt was incurred.
Finally, they only look at federal spending. This is a bit more defensible, but I still think they're wrong to do that. We pay taxes, and we get government services. People care about what they pay and what they get, not about who takes care of the details.
I concede the $94 billion in veterans' benefits and the proportion of the debt interest which can legitimately be attributed to military spending, and also that there may be some relatively small expenditures here and there which could legitimately be considered military expenditures but which are not officially categorized as such. Together these may bring military spending up to about 25% of the federal budget and 16-17% of total government expenditures (federal, state, and local).
For example, the cost of the entire Iraq and Afghanistan Wars are OMITTED from the military defense budget.[/url]
Not true. While they were not budgeted for ahead of time, they are included in the retrospective figures I cited earlier. According to the WRL link you provided, spending on the Iraq and Afghanistan wars in 2009 was $200 billion. A lot of money, but there's plenty of room for it in the $660 billion spent in the "National Defense" category in 2009.
Not to mention, adding a new theater of war is only increasing the amount of military spending to ridiculous proportions.
"Sen. Carl Levin (D-Mich.), chairman of the Senate Armed Services Committee, said Wednesday that he had asked the Defense Department for an accurate estimate of the cost of the mission since the ballpark numbers being circulated, including one of nearly $1 billion, seemed too high."
A billion dollars is a lot of money to you and me, but it's less than 0.2% of total military spending in 2010. If operations in Libya are expanded significantly, it could eventually become a significant expense. At the moment it's a statistical blip.
In fact, the exact opposite is true. Since World War II, military spending has been steadily declining as a percentage of GDP, while social spending has been steadily rising. Military spending has increased somewhat since 2001, but is still fairly low by historical standards, if not as low as I would like it to be. Meanwhile, social spending is at an all-time high.
Case in point: What about the budget proposal did they think worth calling out specifically? A 50% cut in LIHEAP spending, a $300 million cut in "community development," and limiting an expansion of Pell Grants. Not a cut. Limiting an expansion. Those are the best examples they could find to illustrate just how awful the proposed cuts were.
Well, LIHEAP's funding was doubled back in 2009, so the proposed cut would have pushed it back to 2008 levels. And in fact the 50% cut never actually happened. There's a big difference between a budget and a budget proposal.
So of the three big headliner cuts, one didn't happen, one was tiny, and one was never planned to be an actual cut at all. We're all gonna die!
Tl;dr version: It's best not to repeat as fact allegations which you have not personally verified from a primary source.
