President Obama is poised to sign off on a new internal review of U.S. nuclear weapons strategy that would reduce the arsenal by one-third, resulting in billions in savings to the Pentagon and Energy Department.

The recommended reductions were included in a draft version of a classified decision directive compiled by top defense and national security officials inside the White House, according to a report by the Center for Public Integrity issued Friday.

While the president has yet to officially approve the directive, including the recommended one-third cut to the nuclear arsenal, sources tell CPI Obama has voiced no objection to the directive's findings.

Representatives from State Department, Strategic Command, the Joint Chiefs of Staff and the office of Vice President Biden also played a part in drafting the directive.
