Some background on that F-35 flying money pit......

There's a couple of good articles on Wikipedia that provide more insight on it:-

And this one, about Lockheed Martin, the prime contractor:-

The F-22 Raptor was probably a better aircraft, if its avionics were updated
to present technology.

And all of this ignores the fact that fighter aircraft cruising around looking for targets to shoot at is basically a very expensive trip down Memory Lane. 
Today's technology leans more toward ICBMs and unmanned drones and cruise missiles, and other forms of remote-control warfare, because we hate to look our enemies in the eye while killing them. And they feel the same about us.
So we've developed what's basically very lethal video games with which to do all that while never looking anyone in the eye. There'd be a hell of a lot fewer wars if we had to revert to the old hand-to-hand combat methods of actually besting our opponents in physical combat. Maybe, we ought to think about that. The human race is going to self-destruct soon enough anyway. Our numbers and our pollution are taking care of that already.
