"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."

"Nothing in the New START Treaty constrains our missile defense efforts."

"this announcement is as convincing an answer to the efforts undertaken in Tehran, over the last few days, as any we could provide"

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