President Obama has made reducing the U.S. nuclear deterrent a primary focus of his administration. In 2010, he negotiated a treaty with the Russians that, for the first time in history, required only the United States to reduce its deployed nuclear forces.

He then stated he would immediately seek even further reductions to U.S. nuclear forces. Proposals for those reductions, according to press reports, include going as low as 300 deployed nuclear weapons — an 80 percent reduction.
