Jane Harman: “I think leaving the deal on a unilateral basis...further isolates us and that's a mistake in terms of U.S. strategy.”

Should it have addressed Iran's other malign behavior? Yes, it should, and it still could, if this side agreement were entered into.

The American people deserve a voice in this. They have to understand what the trade-offs are in terms of resources and loss of life.

I do think, as you said, that decertifying this deal or at least in some way pulling away from this deal is going to make it harder to negotiate with the North Koreans.

I think we should be very, very careful, given the Iraq experience, and if the people of Iran who elected their government by more than 50 percent in a four-way field want to change their government, then let them do that.
