John Kerry actually said...

Iran reaffirms that under no circumstances will Iran ever seek, develop, or acquire any nuclear weapons.

I believe they will be supportive of this, and I was very heartened to see...

A vote of disapproval in the absence of a credible alternative, would, after 10 years of effort, be self-defeating for our country.
