BYRON YORK: Jeb Bush's disastrous defense of the Iraq War.

Forget Jeb Bush. And forget this nauseatingly obvious hypothetical 'gotcha' question. The correct answer, which I wish someone with big brass balls ovaries on the Republican team would smash back to the questioner is this: "It's a stupid hypothetical, since if we had known then what we know today -- that Iraq had no significant arsenal of WMD -- the question of invasion or no would never have occurred."
