[1] NAPF's mission is to "educate, advocate, and inspire action for a just and peaceful world, free of nuclear weapons."

In 2014, the Nuclear Age Peace Foundation consulted with the Marshall Islands when it filed cases against the nine nuclear-armed countries (United States, United Kingdom, France, Russia, China, Israel, India, Pakistan, North Korea) in the International Court of Justice and U.S. Federal District Court.

The lawsuits make the central claim that these nations have failed to comply with their obligations under international law to pursue negotiations aimed at the complete elimination of their nuclear weapons.

Article VI of the NPT requires that parties "pursue negotiations in good faith" aimed at "complete disarmament."

The lawsuits contend that the other four countries, while not bound to the NPT, are obligated by customary international law to pursue nuclear disarmament.
