The vast majority of the comments I am reading on this site are not stating this. The vast majority, even the Americans, are agreeing that this is a bad decision. Unsure where you got this from.
I think he is referring to the F-35 only here. On military discussion forums it is the consensus that the F-35 is superior to everything else out there with the only exception being that the F-22 has superior air to air combat capabilities.
I have seen interviews with Norwegian pilots responsible for integrating F-35 into Norway’s airforce. Reading between the lines was that it seemed “complex”. I’m not site it is buggy, or overly complicated or what.
There is currently no drone that can replace everything the F-35 does. There might be one in the future, and it will likely be the most expensive aircraft ever made (see the two NGAD programs' unmanned components)
No drone can take out a CRAM (aka: RADAR aimbot shooting bullets into the sky).
Meanwhile, a helicopter with an anti-radiation missile can take out CRAM, let alone a stealth F35. F35 (and F16) are the next step after helicopters: you send F35 when enemy antiair is good enough to threaten helis.
