"The failure to ratify and move ahead with this will certainly set back the prospects for United States-Russian cooperation."

"I believe our chances of proceeding to reductions on tac nukes would be zero if we do not ratify and put this treaty into force."

"Thus, my professional judgment is that U.S. security would be best served by the Senate providing its advice and consent to ratification."

"This treaty improves our security because it increases certainty, stability, and transparency."
