Bush opposes most things that are good for America 🇺🇸
Bush used the WOT as cover for establishing mass electronic surveillance of US citizens via the Patriot Act (knowing that one of the other "Five Eyes" would eagerly help to circumvent any pesky domestic legal barriers).
The WOT was also used as an excuse to bring in an entirely new class of invaders who are completely oppose American culture and norms, observant (and mainstream) Muslims.
But the most pernicious actions of the Bush II administration was establishing the Department of Homeland Security, which unconstitutionally usurped the responsibility of our Nation's borders from the military, and transforming armed invasions by drug cartels into civil misdemeanors.

When 9/11 happened they had the Iraq plans in the can and just whipped them out for the occasion for Bush to use as a response to 9/11 alongside Afghanistan which in theory made more sense.
But Afghanistan was just another Vietnam which should have made it stupid coming out of the gate but the emotions of 9/11 got in the way of common sense.
