Once you invade a country you're committing to a certain responsibility to do right by it and the people living there. Either follow the Prime Directive or don't, but you can't just choose whimsically based on whatever is convenient in the moment. Blame the Bush admin if you really want to blame someone.
How does the prime directive apply when you are attacked directly.
I do agree that Bush deserves the blame for turning what should should have been a hunt down and destroy Al Qaeda mission into a sprawling invasion of various countries in the middle east
Afghanistan or the Taliban didn't attack the US – bin Laden did, who had no position in the Afghan government. Taliban refused to extradite Bin Laden to the US, and the US refused any compromise such as extradition to another country. All of that is a rather different thing than "they attacked us".
Regardless, Obama, Trump, and Biden had to deal with the situation as they found it, whether they agreed with the lead-up or not.
