well it was never about getting rid of shitbag regimes.
It was never about oil either.
Rather about establishing and maintaining Pax Americana.

Al Qaeda's project just happened to collide with and energize
the neocons project for a new American Century.
WHoever planned 9/11 is not a simpleton, he must have known
that the US would respond militarily and aggressively, at Al Qaedas
bases in Afghanistan. Did anyone expect the US to suddenly withdraw and start a new isolationist policy? of course not. So why would Bin Laden
do it. The obvious answer is to instill more anger in the muslim world and get more recruits for their cause. The trouble is that Afghanistan fell quickly,
because the US mostly fought an air war, and co-opted the Northern Alliance and other warlords to do their work.

On the other hand, it must have been a gift to Bin Laden to invade Iraq, and judging from the number of foreign muslim recruits that flocked to Iraq, it was exactly what Al Qaeda wanted.

All the muscle flexing, the biggest and most advanced military in the world, attacking a fifth rate 3rd world army, cancelling the ABM treaty, and developing small usable nukes etc. is all intended to show
AMericas power to everyone else.

Of course it never works, (just look at all the other empires consigned to history, Rome, Spain, Ottoman, Britain) in the end economics trumps all. And with Walmart exporting manufacturing jobs to CHina, software and information services going to INdia, and the ongoing Republican destruction of the American middle class you can see where its going.
