The biggest lie in history?

Hmmm. Bush’s lies, both of the Bush’s, about Iraq, WMD, bin Laden, those were bad. Powell recanted though. But, true they cost a lot of lives. He got votes for his war spending bill but i think he lied to get it, he spent more than he said he would. And he created a quagmire.

Was he lying, or did he believe those regimes were a threat?
