Currently we spend 40 cents of every military dollar spent on earth. We out spend our nearest rival 4 times.
How much is enough? 5% of our GDP? 10%?
If you want my head to explode say “what ever it takes”.
The purpose of our Government is defense of our nation. So, I’d say at least 90% of our budget should go to Defense. Don’t misunderstand though, there should not be any other department, just the DOD, period. The states should take care of everything else, on a state by state basis.
