And why would you have a small very expensive fleet of fast moving drones that can carry bombs? Targets/training only? Wouldn't that be wasteful? Wouldn't those be expensive to just send in for recon or shooting down a plane or even a bombing run that they could use other manned aircraft for? What would they be best suited for?

I'm not against the USAF trying to improve its defense.
But, if a remote-controlled nuclear-armed jet were controlled by an AI, or by a terrorist, that would be a big problem.
I understand that it's expensive to find and train good pilots, and it takes a long time. They are a limited resource. So, I can see why you'd want to replace them with drones- you save a lot of money, could expand the fleet more quickly and with less expense, eventually.
But, that expense is a safeguard. It keeps really bad things from being able to happen. We shouldn't be making anything nuclear-capable more easily remotely-controllable. And if the US does it, others will. Even if the US were to be completely safe about it, other states might not be.
