I admit my numbers were rough guesses. That said, I don't think really anyone can know--e.g. "black budgets" etc. But basically if your numbers are somewhat correct, I was only 2x off. You're stating 12.5% goes to essentially military. That's a lot. In addition, it seems that veterans are one of the biggest, if not The biggest entitlement--again, more military.
...a quick search shows this article saying 16% is going to defense:

I also read recently something to the tune of: 70% of our national debt comes from military related expenditures from the 2 Bush presidents, and by 2020 interest payments will go from 5/6% to 10/12%. What about the principal? When does that get factored in?
I admit I'm not an expert on these matters (as i chose to focus on what i can change). However, there does seem like there are various discrepancies here--so what if the number is closer to 18% vs. 25% or 12.5%. It's way way way too much and would make a difference--more importantly in the lives and hatred abroad we would be sparing. We didn't fix or help anything in Vietnam and no matter what they say, we haven't in Iraq or the Middle East--our selfish financial losses aside.
However, now imagine instead of taking out credit for those wars, we invested. That would be paying major dividends that would further counteract these numbers. Now imagine we invested in ourselves (not just financial instruments)--the potential is far higher.
Military spending without a doubt has put a damper on our progress and perhaps the sole reason America may never reach the potential it once had. America was never great--rather, it had potential to be great. Now it's mediocre, and other countries are eating our lunch, and rightfully so. Not that the world is zero sum--but we'd stand to benefit from taking a page from their playbook (e.g. nordic countries, etc). We have shitty education. We are well on our way to becoming idiocracy. We unfairly lock up way too many people for far too long in shitty prison conditions (and then let corporations exploit them for cheap labor!). We have plenty of money but we spend $11 Billion on the Airforce One and Marine One fleet. That would put $33 in every american's pocket. Our expenditures from the Middle East since 9/11 would put like $30k in each american's pocket. If that was $5k over 6 years, that's life-changing money for half of america. ..This country is just ridiculous. Paying 50% of your earnings as taxes in California is absurd. It's a crime. There's no point owning (why pay that 1% property tax), there's no point making lots of money. Just rent, make far less, and work way less hard--what sort of incentive is that! That said we have a problem of working too hard and too much in this country (at least for people of a certain class)--so from that perspective perhaps it's a good thing. I rather make whatever that sweetspot income is from a taxation point of view ($75k?), rent, not try to make billions from my startup and live a simple life.
And yes, we should cut 90% of our military. Instead, we maintain an arsenal of super modern nukes and a small extremely efficient elite navy-seals-like task force. + Yes, the best cyber-security outfit on the planet (while somehow keeping surveillance on citizens to a minimum). But fire most people in camouflage uniform.
Gun-to-your-head "peace" is not peace. There is no world peace. This "peace" we have enforced will not less forever. As soon as china knows they can beat us they will make us pay for our sins in one way or another. We need to become more cooperative now and show the world how to act NOW while we're on top, cuz once we're not we won't be able to set such examples. We aren't cooperative. We are forceful. Again, it's gun-to-your-head peace. The lessons of history clearly indicate to me that it's a recipe for disaster as those hungry come up from behind you and use the ugly strategies they learned from you against you. These are basically life laws we're talking about here. So we aren't setting a good example. We haven't created true peace. It's temporary peace. And things could get catastrophic unless America completely changes its ways. I'm not even saying gun-to-your-head "peace" wasn't needed to get to this point, i.e. the most peaceful point in human history. I'm saying it's run its course, and if we continue to operate that way, we'll regress--and regress bad!
So why not save some money (AND SOME LIVES) and show some real leadership. Real leadership is about taking risks. Risks and faith are what it's all about. As powerful as the US is, it has an opportunity to set that stage. That would be the turning point in human history that civilization has been looking for. It's the next evolution. We have that opportunity right now. We are on the precipice of a turning point while things are still relatively stable. Cut the military, we don't need it. Save us some dollars and focus on education.
