It's all because of G.W. only because he was the sitting president when the attacks happened.
I don't think a single politician would have stopped a military response somewhere in the world after the 9/11 attack. Does anyone remember how united this country was?
Does anyone remember the anti-Taliban messages in 1999-2001, do you remember Hollywood starlets vocalizing the plight of Afghani women? They were begging for the world to intervene! There was even a Dateline or 60 Minutes special report. They were calling for a regime change! But, the world wasn't interested in helping some women in a tiny, impoverished country half way around the world.
Doesn't anyone remember the mass murders committed by Saddam's death squads (and his two kids)? How about the revenge taken out upon the Kurds for believing that the USA would actually support them in a coup attempt. There were plenty of photos of gassed women and children. But, the world stood by and ignored it.
Nobody even cared when Saddam continuously thwarted UN weapons inspectors trying to do their job. If we'd had any cajones, he'd have gotten an ultimatum and the next facilty he blocked access to would have gotten leveled by several cruise missles. But, that was a UN mission and not just a US operation.
So, we get that regime change in both Afghanistan and Iraq; and nobody is happy. It just goes to show how little anyone actually cares about the world beyond their own circle of friends and we don't remember the details of significant events even a year or two earlier.
It's no wonder everyone is blaming Bush and we've all forgotten the miss cues of Clinton, Bush, Regan, Ford, Carter, Nixon, Johnson, Kennedy, et al.
Go figure.
