It now seems probable that there will be enough support in the US Senate to ratify the new START treaty. This would be a victory to the Obama administration. However, according to analyst Robert Kagan, the treaty would also be beneficial to republicans:
New START, whatever its flaws, is not a threat to U.S. security. The three previous arms-control treaties, all negotiated by Republican presidents, cut deployed nuclear weapons from near 12,000 to around 2,000. New START reduces the totals to 1,550. Passing it will neither produce a nuclear-free utopia nor disarm the United States.
But blocking the treaty will produce three unfortunate results: It will strengthen Vladimir Putin, let the Obama administration off the hook when Russia misbehaves and set up Republicans as the fall guy if and when U.S.-Russian relations go south.
