With the removal of the ban on Iran exporting arms, Iran is going to face fewer impediments to arming those proxies.

I think that there will be new challenges from the Iranians.

I think somebody used it, this permissive environment that we have created, which we acknowledge that Iran is going to continue a program of nuclear development, ballistic missile development regardless of the consequences.

if we take our eye off this ball, if we fail in any way to relentlessly enforce what we have got in terms of both U.S. unilateral and multilateral abilities to constrain Iran's actions, they will take that as a clear signal that we have…

I think tireless work with our P5+1 partners as well, as well as continuing to enforce what sanctions authorities we have and extend them as a key piece of this.

I expect that we will work on a relentless and bipartisan basis to ensure that our allies understand that we intend to continue to enforce sanctions against Iran's ongoing bad behavior in the region.

When the United States steps up, acts with determination, it reassures our allies.

I will continue to call for Congress to do three things.

the demands of the JCPOA... are going to place a very special responsibility on the IAEA.

I think it is incumbent on us to work closely together in the legislative branch to ensure that we take greater action to strengthen our unilateral sanctions against Iran's ballistic missile program.

I commend the administration for its recent actions, I encourage that they continue, and I encourage that you enhance the implementation of the nuclear accord.

Iran's recent ballistic missile tests... demonstrate that the nuclear deal will not change Iran's behavior.

I remain deeply concerned that Iran continues to expand its influence in the Middle East and increase support for its terrorist proxies.

I expect Iranian cheating to be initially marginal and initially modest, and if they are not responded to promptly and effectively in a coordinated way with our allies, we will lose whatever advantage we may have gained through this…

I think what was the strong point of the Obama administration in the last 8 years was that we built an international coalition that exacted costs on the Iranian regime.

Saying is good; doing is better.

I am relieved by the long overdue release of five Americans from unjust Iranian custody.

I think thinking that unless there is something so out of bounds that it is egregious that we are going to be able to easily put that coalition back when everybody is in Tehran trying to do business right now is just not going to happen.
