GW Bush/ Cheney LIED us into the War in Iraq.

The Iraq War was no innocent mistake based on faulty intelligence, Krugman argues compellingly. "America invaded Iraq because the Bush administration wanted a war," he writes. "The public justifications for the invasion were nothing but pretexts, and falsified pretexts at that. We were, in a fundamental sense, lied into war."

And we knew it—or certainly should have. Krugman:

The fraudulence of the case for war was actually obvious even at the time: the ever-shifting arguments for an unchanging goal were a dead giveaway. So were the word games — the talk about W.M.D that conflated chemical weapons (which many people did think Saddam had) with nukes, the constant insinuations that Iraq was somehow behind 9/11.
