On Sunday, in talks with the interim Iraqi leader Iyad Allawi, Tony Blair has actually said that we face a "new conflict" in Iraq.
Here's a linkThis is a new departure for Blair, who has previously been keen to stress how well things were going, but the chaos of the last month or so has clearly registered, so he is now, in effect, admitting that he (for one, but by implication including George W Bush & the rest ot his administration) underestimated how difficult the aftermath of the Iraq War would be, and saying that a new phase of "war" - or, if you prefer, "major combat operations" has begun.
While he has suffered a predictable backlash of "we told you so" from people who did, indeed, tell him so before the March 2003 invasion, it is perhaps still easier for Blair to publicly face up to the truth like this than it is for Bush.
After all, he didn't make a big showy broadcast to the listening world from an aircraft carrier in front of a banner saying "Mission Accomplished".
The plain truth is that whether or not the removal of Saddam was justified, the Coalition of the Credulous (I'm there too - I believed Iraq had WMD. Saddam took us all for mugs

) did not make sufficient plans for what happened after Saddam was removed.
Many critics of war based their criticism on this fact alone (it was the public position of France, for goodness' sake!) and are entitled to make hay now.
It
should (in the sense of "ought to if there is any justice in the world") cost both Bush and Blair electorally - Bush more than Blair, if GWB can't steel himself very soon to eat some humble pie in public, as Blair has just done.
It's one thing to get suckered in along with everyone else - we all thought Iraq had WMD. It's quite another to be told in detail about a mistake we are about to make and ignore that advice our of sheer bloody-mindedness.
So no, I don't think Bush is being honest with the American public on Iraq. It's not yet unsalvageable, but he needs to make an even bigger show of his humility and willingness to admit mistakes than he did over his hubris on the flight deck.
