WASHINGTON (Kyodo) The United States should launch a full dialogue on nuclear issues with Japan, parallel to Washington's efforts to hammer out a new atomic arms limitation deal with Moscow, according to a congressional report released Wednesday.

The report by the Congressional Commission on the Strategic Posture calls on the U.S. to lead the way in helping to achieve nuclear disarmament, but acknowledges the country will need to maintain its nuclear deterrence capability for years to come.

The commission, chaired by former Defense Secretary William Perry, unveiled the report to put forward recommendations to the administration of President Barack Obama on the future shape of U.S. nuclear weapons policy.
