We would like to have friendly regimes with enough broad participation of their populations to maintain long-term stability, so that we would have not only access to the region's wealth, but we would be able to ensure the security of our good friend Israel.

These are all elements, but the main thing we can do in the Middle East is encourage the reformist elements.

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.

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