Ish.

The main cause of U.S. debt is four fold. It's military spending, medicare, social security, and interest on the debt.

The problem with interest is that it only grows bigger as time goes on.

With military spending it's not just the planes and bombs, but mostly the salary of people in the military, particularly those who spend 20 years in the military then collect a pension for three times that timespan. There's a reason businesses in the U.S. moved away from pensions back in the 90's and it's because it's an unsustainable business model and is like having twice the staff on payroll.

For social security and medicare, the biggest problem is that the money was collected over many years. It was supposed to be used to pay them back, instead presidents like nixon and clinton dipped into the funds (quite heavily) to make it seem like the deficit wasn't nearly as bad. (nixon used it to fun Vietnam, clintion used it to show that we weren't running a deficit. Which is true, at the time, we were taking in more money for social security than we were spending. Just that, in the long run, it doesn't work that way.)

That's the funny thing. All of what i just listed is 88% of the U.S. Budget. Even if we cut all federal spending except for those 4 (FBI, white house staff, air force one, IRS, USDA, post office, subsidies for companies, EVERYTHING) then that'd only be 12% of the budget cut.
