There's no common sense reason this would reduce government interest payments.
There are many common sense reasons it would specifically not impact interest payments. For example, if we can carry the interest load on the current tax base just fine, increasing taxes will cause spending to rise, not stay the same. Also, if rising taxes are perceived as anti-corporate, bond prices will fall, and interest payments will rise anyway.

One perspective of the military is that it is welfare that is acceptable to Republicans. The vast majority of that cash was spent in the USA. You can make a tired reference to moving cash overseas, however many billions it was. But you are ignoring the main point.

What if military spending were welfare, for the most part?
Like 999/1,000 DoD employees will not be in a meaningful defense or combat role.
What if you live in a shithole and life was shitty and you needed an out? You join the military.
What if you're just broke? You join the military.
It's culturally acceptable welfare for the vast majority of people.
Social media has robbed people of their common sense.
