The thing is, other than failing to defend bases from incompetence, I am not sure the US military really was shown to be weak here.
What has been proven is that you can't bomb a country into submission, which even though the US desperately wants to believe works does not work, has never worked and never will work.
That doesn't mean the US military is weak necessarily though the top leadership has now been mostly replaced with incompetent people which is genuinely terrifying.
