F-35 aren’t the crucial component to winning the kind of wars in Iraq or Afghanistan. They also aren’t the kind of weapon that are important to defend Taiwan. They are just what the airforce culture wants instead of being a choice made by a hypercompetent military.
I mostly agree with your perception of state (or something) competence, but this seems to me like a sloppy argument? True, the US does have to prepare for the most likely wars, but they also have to be prepared for all other wars that don’t happen because they were prepared, aka. deterrence. The F-35 may not be the most efficient asset when it comes to e.g. Taiwan, but it’s useful in a wide range of scenarios, and its difficult to predict what exactly one will need as these platforms have to be planned decades in advance.
Not sure how to put this in a way that isn’t overly combative, but since the only point you made where I have domain specific understanding seems to be sloppy, it makes me wonder how much I should trust the rest? At a glance it doesn’t look like artight reasoning.
EDIT: As a sidenote, what the airforce culture wants is in itself a military consideration. It’s often better to have the gear that works well with established doctrine than some other technology that outperforms it on paper.
I’m not an expert either, and I won’t try to end the F-35 debate in a few sentences. I maintain my position that the original argument was sloppy. “F-35 isn’t the best for specific wars X, Y and Z, therefore it wasn’t a competent military decision” is non sequitur. “Experts X, Y and Z believe that the F-35 wasn’t a competent decision” would be better in this case, because that seems to be the real reason why you believe what you believe.
