In 1994 the United States, Russia and the United Kingdom signed the
Budapest Memorandum on Security Assurances
That memorandum on security assurance against threats to the sovereignty of Ukraine resulted in Ukraine giving up the world’s third largest stockpile of nuclear weapons and agreeing to the
Treaty on the Non-Proliferation of Nuclear Weapons.
Since Russia is now violating its commitment under the Budapest Memorandum and the United States and United Kingdom seem unable or unwilling to go the aid of Ukraine, we should give back to Ukraine the nukes they had and need to defend themselves.
