Summary

If the President plans to change the total U.S. nuclear stockpile or the number of deployed nuclear weapons by more than 20%, the President must first start a Nuclear Posture Review. This does not apply if the change is required by a treaty the Senate approved under Article II, section 2. The President must give the review’s terms to the congressional defense committees before starting and must send the finished review to those committees before making the change. The review must be unclassified but can include a classified annex. New START is the treaty signed April 8, 2010, and in force February 5, 2011.
