The reason the US defence budget is so sky-fucking-high is because we effectively pay for everyone's military, though.
I doubt the other budget line items would see an increase with defence cuts, but we certainly don't need the entire defence budget for just our own sake. America doesn't need 11 nuclear aircraft carriers or nearly 2500 F-35s, among other excesses.
Also: Attitudes like yours sincerely make me want to see America First pushed more literally to the point of leaving those who don't appreciate us to fend for themselves. Japan, EU, and so on.
Obama already declared we aren't the world police anymore, for better or worse.
Any talk that assumes the US defense budget is massive is silly. It's approx 12% of the federal budget and 3.4% of the nation's GDP. It seems large because the US is rich and it seems large compare to the EU because most of the EU, besides Poland, decided it was a lot cheaper to have a token force and leave the real work to the Americans.
