On balance, however, I believe the nuclear deal will deliver more advantages than disadvantages to the U.S.

I don't think it's impossible, but it would depend on a strong and assertive and self-confident American President at the time.

I believe that the nuclear agreement reached by the United States, its P5+1 partners, and Iran is a good deal.

If the United States rejects the deal now, it will not be possible to negotiate a new one.

I hope members of both parties will work with the Administration to strengthen the ability of the United States to implement the agreement successfully and to contain simultaneously Iranian power in the Middle East.

We should create, in effect, a two-track American policy towards Iran in the future.

I remain opposed to this compromise. I don't think it's in our interest.

President Obama should reaffirm publicly and in the most unmistakable terms, his readiness to deploy military force to strike Iran should it violate the agreement and seek to race toward a nuclear weapon.

I hope, maybe as early as tomorrow, when the President makes his speech, that the President will threaten publicly and unambiguously that the United States would and should use force against Iran.

Establishing a tough-minded policy now is the right way to convince Iran there will be immediate penalties should it not implement the deal fully and completely;

I think it does, thanks to the joint efforts of Congress and the administration to put the sanctions regime in place.

In my judgment, the Joint Comprehensive Plan of Action (JCPOA) negotiated by Secretaries Kerry and Moniz is a solid and sensible agreement.

I believe it does, thanks to the efforts of Congress and the administration to leverage sanctions in pursuit of that goal.

I mean, we are just giving it for every reason in the world. I mean, they have problems here, problems there.

I think there's plenty of reason, actually, to believe that it would not.

I thank Congressman McKinley for his leadership on this issue and in our great State of West Virginia. I thank Congressman Barr for his great comments and for his telling some personal stories about how this affects real Americans from…

I think there are greater risks in rejecting this agreement, because it would free Iran from the considerable restrictions.

But, let me just say that in my State of West Virginia, drug abuse is the number 1 killer.
