This START treaty is an evolution of treaties that have been negotiated in previous administrations of both parties. And its principal provisions are an elaboration or a continuation of existing agreements. Therefore, a rejection of them would indicate that a new period of American policy had started that might rely largely on the unilateral reliance of its nuclear weapons, and would therefore create an element of uncertainty in the calculations of both adversaries and allies. And therefore, I think it would have an unsettling impact on the international environment. _[5/25/10]

There's no getting around it: Failure to pass START will help empower Putin . . . On Iran, Russia will become less cooperative . . . Russia's refusal to deliver the S-300 air defense system to Tehran and its earlier agreement to allow the U.S. military to ship material to Afghanistan across Russian territory have been the reset's big tangible payoffs. _[11/12/10]

Without data from new START, would that create more uncertainty for us about Russia? Certainly the country would not get as much information that the monitoring program would provide through new START. _[7/15/10] 

George Miller
^{Director, The Lawrence Livermore National Laboratory} 

I think that it is certainly true that the START treaty that is under your consideration does offer the ability to understand, provide more data on what's going on in Russia with their systems. As a technical person, data is always valuable and so it will certainly reduce our uncertainties. _[7/15/10]

^{Former United States Senator, R-NE} 

If this were to go down, the ripple effect consequences around the world would be the worst possible outcome we've seen since World War II. It would set in motion the disintegration of any confidence in the leadership of the two major nuclear powers to deal with this and it would set in motion a disintegration of any structural boundaries and capacities to deal with this. This would devastating not just for arms control but for security interests worldwide. _[7/19/10]

U.S. ability to conduct on-site inspections will continue to be suspended . . .U.S. is obliged to plan on worst-case scenarios with regard to our own deployments. _[11/15/10] 

^{Deputy Commander in Chief and Chief of Staff of U.S. Strategic Command (former)}

Without it [New START] we'd be poorly equipped to monitor Russia's arsenal. _[7/19/10]
