The United States says it doesn’t believe its Nuclear Posture Review released Tuesday will result in North Korea trying to bolster its own nuclear capabilities.

In a briefing before foreign correspondents Thursday, Robert Einhorn, special adviser on nonproliferation and arms control to Secretary of State Hillary Clinton, said the report makes assurances to nonnuclear weapons states who comply with the nonproliferation treaty (NPT). He said the report doesn’t affect any of the countries not covered by the security assurance, including North Korea.

James Miller, principal deputy undersecretary of defense for policy, who also attended the news conference at the Foreign Press Center, said the report should encourage Pyongyang to go the opposite direction and desire to be one of the states compliant with the NPT.

The Obama administration’s new report declares that the U.S. will not attack nonnuclear weapons states with nuclear warheads, but that this does not include North Korea and Iran, which the U.S. says have failed to abide by international nuclear nonproliferation obligations.
