Well reasoned NYT editorial.

A Pause for Hindsight

Excerpt:

"Saddam Hussein was indisputably a violent and vicious tyrant, but an unprovoked attack that antagonized the Muslim world and fractured the international community of peaceful nations was not the solution. There were, and are, equally brutal and potentially more dangerous dictators in power elsewhere. Saddam Hussein and his rotting army were not a threat even to the region, never mind to the United States.

"Now that we are in Iraq, we must do everything possible to see that the country is stabilized before American forces are withdrawn. But that commitment should be based on honesty. Just as we cannot undo the invasion, we cannot pretend that it was a good idea - even if it had been well carried out."
