The Prohibition On The Use Of Force For Arms Control: The Case Of Iran’S Nuclear Program, Mary Ellen O'Connell, Reyam El Molla

Mary Ellen O'Connell

International law does not permit the use of military force against Iran to attempt to end its nuclear program. The resort to military force in international relations is covered first and foremost by Article 2(4) of the United Nations Charter.

Preserving The Peace: The Continuing Ban On War Between States, Mary Ellen O'Connell

These rules restricting force are found in treaties (especially the United Nations Charter), customary international law, and the general principles of international law. In other words, the …
