WASHINGTON — President Obama will use his State of the Union speech on Tuesday to reinvigorate one of his signature national security objectives — drastically reducing nuclear arsenals around the world — after securing agreement in recent months with the United States military that the US nuclear force can be cut in size by roughly a third.
Obama, administration officials say, is unlikely to discuss specific numbers in the address, but White House officials are looking at a cut that would take the arsenal of deployed weapons to just above 1,000. Currently there are about 1,700, and the new strategic arms reduction treaty with Russia that passed the Senate at the end of 2009 calls for a limit of roughly 1,550 by 2018.
But Obama, according to an official who was involved in the deliberations, ‘‘believes that we can make pretty radical reductions — and save a lot of money — without compromising American security in the second term. And the Joint Chiefs have signed off on that concept.’’
The big question is how to accomplish a reduction that Obama views as long overdue, considering that Republicans in the Senate opposed even the modest cuts in the new arms reduction treaty, called New START.
The White House is loath to negotiate an entirely new treaty with Russia, which would lead to Russian demands for restrictions on US and NATO missile-defense systems in Europe and would reprise a major fight with Republicans in the Senate over ratification.
Instead, Obama is weighing whether to announce unilateral cuts or, more likely, to attempt to reach an informal agreement with President Vladimir V. Putin of Russia for mutual cuts within the framework of the New START — but without the need for ratification.
Obama’s national security adviser, Tom Donilon, is planning to travel to Russia next month, officials say, to lay the groundwork for those talks. Obama and Putin will hold two summit meetings in the early summer.
The nuclear reduction plan has been debated inside the administration for two years, and the options have been on Obama’s desk for months. But the document was left untouched through the presidential election.
