An international panel on nuclear nonproliferation is calling on world leaders to reduce the number of nuclear weapons from more than 23,000 at present to 2,000 or less by 2025.

Yoriko Kawaguchi and Gareth Evans, the former Japanese and Australian foreign ministers who cochair the International Commission on Nuclear Nonproliferation and Disarmament, submitted a report with that goal to Prime Minister Yukio Hatoyama and visiting Australian Prime Minister Kevin Rudd in Tokyo.

Titled "Eliminating Nuclear Threats," the report consists of 76 recommendations stemming from a three-day meeting in Hiroshima in October and aims at building an international consensus in the runup to a Nuclear Nonproliferation Treaty review conference at the U.N. in May.
