Jane Harman: “But imposing sanctions and continuing to impose them on Iran's malign behavior in the region, which is permissible, is…”

I think Congress has to enact an authorization to use military force for the region, which would identify the trade-offs and how to create a strategy for United States leadership that puts maximum pressure not just on Iran.

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.

If you're Kim Jong-un and you're watching this and thinking oh, here was an international agreement led by the United States in which they promised to give up their nuclear program in exchange for certain things.

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.
