It's different. 9/11 was an outside foe, which was dismantled by US forces, and its leader was executed. America "won" against the perpetrators of 9/11 in the conventional sense.
You cannot defeat MAGA the same way: the "enemies" are among us, and they aren't going anywhere.
From my point of view as a European asking if myself if or when I will be able to trust the USA in the future, the Taliban is to Afghanistan as MAGA is to the USA.
You're the outsider, to me. The pre-9/11 Taliban were seen as "kinda weird but we can do deals, oh dear aren't they awful, never mind", the post-9/11 were not even worthy of talking to. The USA is currently in a similar "pre" state, an invasion would make it a "post" state.
