One of the authors is a retired general, so he probably knows a bit more than us internet randos. Still, the last paragraph says: "The lesson of the Iran campaign is that the F-35 performed superbly in exactly the kind of fight it was built for." I feel like it's hard to gainsay the utility of the F-35 when it's useful in a real war we're actually in.

The author's main argument against the F-35 is that it can be easily destroyed on runways now, as drones and missile developments have outpaced missile defense, leaving the US and US allies vulnerable to a preemptive strike by China.

That might be true, but it's also strategically valuable to diminish the military capabilities of allies of China (e.g. the Iranian theocracy), which may make up for the tactical weaknesses of the F-35 against China in a direct confrontation. It's also possible that drone/missile defense will catch up (e.g. lasers), but that's hard to say at this point.
