You’ve got to be kidding us.

Tiny fraction?

There’s some people (not This Guy—please!) who’d like to know what you’re smoking.

Yes, tiny fraction.

Current US defense budget is @3.5% of GDP. In the 1950s it was in the range of 8-9% of GDP. And, IIRC, procurement was a higher fraction of the budget than these days. Personnel costs have tended to increase, proportionately, relative to procurement. Defense industries have declined, a lot, relative to the general economy.
