Obviously it stops with GWB. That applies to everything that happened before he took office, during and every year since he left office. It's all GWB's fault, and your Obama is the only one who can keep us safe. I get it.
You like to get absurd with you arguments, but thank you for admitting he does have some culpability in the matter. It is by no means all his fault, but he is not blameless as you were asserting.
