We went into Iraq because Iraq posed a threat to the stability of the region and was engaged in the process of trying to develop weapons of mass destruction and had links to terrorists.

So, I think even in Saudi Arabia there is movement. And we have to remember that over the years they've stabilized the oil price and that is tremendously important for the economies of the world. I think we have no choice but to work with the government of Saudi Arabia.

There's clearly something to be said for success and following through on your commitments.

And I argued with that intelligence estimate and I think it is a responsibility of policymakers to use their best judgment on the basis of the intelligence they've received.

Policymakers have to make judgments based on the best intelligence they get.

It took us 50 months in Germany, post World War II to go from the end of the war to a national election.

Putin has a lot at stake here and restoring the relationship with the United States, and there are already signs as Sandy mentioned that he's moving in the right direction to begin to ascertain that their trade with Iran is not used for the production of nuclear weapons.

The problem is that neither the M1 nor the M60 or indeed neither any tank, has sufficient ground pressure to drive a [bulldozer] blade into even marginally hard ground.

I wouldn't even know - and I spent three years in the CIA - I wouldn't even know how you'd start a covert action program in a place like Iran. It would be extraordinarily difficult.
