While we're in a speculative mood, just what kind of planes do you think are needed to be a superpower nowadays? Seems to me that a plausible answer is drones, lots of drones, and missiles, with a EW / networking / stealth focused plane to forward-position a human to coordinate them. The F-35 seems to fit that role like a glove.
ICBMs are another potential answer but I have a hard time being angry at war toys that provide intermediate options between "peace" and "destroy the world."
I believe the same would be true for tanks. Lots of small and nimble tanklets remotely operated from stand-off mobile c&c centers.
Remote operation is vulnerable to jamming and anti-satellite weapons.
You could have a plane that goes from point A to B and shoots down anyone that tries to stop it along the way without any remote operation.
And you don't envision any problems with this?
Like Iranian or Korean Boings?
The answer might even change as AI develops.
If I had a budget the size of the US military, I'd want both.
Of course, no one knows that the next war is going to look like until it happens; speculation on what mix of weapons will be most effective is fruitless without combat experience, and we haven't had symmetrical wars with the latest technology since... what, 1973?
Antennas can be turned off in microseconds, but AWACS can't stop being a big fat sitting duck ever.
In case you need to assert air superiority over a better armed adversary then you would need the best fighter planes possible and this F35 will probably not pass the mark.
