Directs the Secretary of Defense to conduct a force analysis for Congress of current and proposed U.S. nuclear forces to determine whether such forces are capable of meeting U.S. nuclear deterrence and defense objectives in the context of current and anticipated nuclear and non-nuclear forces of the Russian Federation and other countries.

States that any agreement with a country or international organization or amendment to the New START Treaty concerning the limitation of U.S. missile defense capabilities shall not be binding on the United States, and shall not enter into force with respect to the United States, unless it is: (1) approved with the advice and consent of the Senate, or (2) authorized by an Act of Congress.

Prohibits the reduction, consolidation, or withdrawal of U.S. nuclear forces based in Europe unless: (1) requested by the government of the host nation, or (2) the President certifies that NATO supports such action and each NATO member state has separately concurred that the remaining U.S. nuclear forces in Europe provide a commensurate level of assurance.
