In addition to the aircraft you cite, the "Left" was determined to destroy the M-1 Abrams. I think they were conclusively proven wrong a little over 20 years ago.
The left tried to destroy the M-1 Tank, the Abrams Fighting Vehicle, the F-16, the F-15 and the especially the A-10 which was much feared by their friends in the Soviet Union.
They pretty much succeeded with the F-22 and now they are making a pass at the F-35.
My guess is that it has proved quite a bit about itself already with the prototypes and first production planes now in service, which is one of the main reasons the progressives need to kill it, usually by driving up its price tag however possible, same as with the M-1, etc.
Their goals and tactics don't change, only the new generation of people those things work on is what changes.
Reagan's warning should always be heeded. The other side figured that out.
They took Reagan seriously. We took him for granted.
