People that make statements like this really didn't put thought into it.
Does anyone believe it costs the same to pay a soldier living abroad? That there isn't logistical costs to it, COLA, etc? Thats just on the surface. Maintenance on the base, equipment, etc.
If the US left NATO, we’d still have a trillion dollar defense budget. There’s no cost savings that would come from withdrawal.
We just wouldn’t have any Allies.
Predatory powers like Russia and China would pick off the weak states and we’d all be worse off.
