At the start of the war no one knew how long it would last or how vast it would turn out to be so it is hard to pass judgement on the aircraft designers for their failures.

If you look at todays aircraft you can also see different ideas expressed by different countries around the world.

Some use the Tornado but I don't see how it would survive other fighters such as F-16, F-18, Migs and Sukoi. The use of the B-52 and B-1 would not work if missles and fighters are around. I would think the use of attack helicopters would be expensive if shoulder launched missles were around. Cargo aircraft would not survive in a missle or fighter enviroment.

Some use jack of all trade aircraft like the Saab. The US is retiring the F-117 which was not a fighter at all.

People say how great a fighter the F-4 was. If both pilots were equal, which would you bet on, the F-4 or the Mig-21 in air to air combat ?

Too many factors to make long range predictions on warfare.
