Frankly, the US can’t afford the F-35. The US infrastructure is crumbling and is slowly dragging down the economy. And the politicians have no understanding of the consequences of ignoring infrastructure.
You will probably continue to spend money your really can’t afford on flashy new weapons and wage war around the globe. But it will become harder and harder to find money until it all ends in tears.
So from an economic standpoint, it makes sense to cancel or significantly reduce the F-35 project and start up a project which is more in tune with the economic realities.
And the US need to look into the rest of the advanced weapons programs and see what can be put on hold until the economic infrastructure has been regenerated.
