RCW: Also in response to President Obama's support for the protesters, Ahmadinejad made a public statement directed to the President. "I hope you [Mr Obama] will avoid interfering in Iran's affairs and express regret in a way that the Iranian people are informed of it. Will you use this language with Iran? If this is your stance, there will be nothing left to talk about."

Given this statement, if Ahmadinejad remains in power, should the Obama Administration still try to pursue diplomatic talks with Iran?

Gen. Clark: I think it's going to be necessary. Let's see how the policy evolves. It's several months before we're ready to really move forward on these issues. Let's see what the situation in Iran is at that time. We don't know. But certainly for the sake of the people of Iran, we ought to continue to hold options open. We shouldn't be foreclosing options at this point, because the alternative is something that would be worse for the people of Iran.
