New START endorsed by U.S. Senate Foreign Relations Committee

The New Strategic Arms Reduction Treaty (START) passed the U.S. Senate Foreign Relations Committee by a vote of 14 to 4. Questions remain regarding when the treaty will be submitted for a vote to the full Senate and whether the Obama administration will be able to garner enough support to secure the two-thirds majority required for ratification. “We have had excellent conversations with senators on both sides of the aisle and we will continue to answer questions and work with the Senate broadly beyond the committee in preparation for the vote that we are hoping will occur in the lame duck session,” said U.S. Secretary of State, Hillary Clinton. The U.S. Administration has repeatedly underlined that the new START, CTBT and the Fissile Material Cutoff Treaty (FMCT) are their top nuclear disarmament priorities. The CTBT is widely viewed to be next on the agenda if START is ratified.

Israel and the CTBT

Israeli Ambassador David Danieli delivers a statement at 2009 Article XIV Conference.

“America’s participation in the treaty does not answer Israel’s concerns, and therefore the approach that suggests that American ratification should automatically result in Israel’s ratification must not be accepted,” argued Alon Bar, former Director of Arms Control in Israel’s Ministry of Foreign Affairs. At the same time, a framework of understanding between Israel and the United States that addresses some of Tel Aviv’s concerns and interests should be formulated, within which “Israeli ratification of the CTBT could be a significant element,” writes Bar.
