Baruch opened his remarks by saying, "We are here to make a choice between the quick and the dead.".^[29] Under the plan, the U.N.'s member nations would have agreed to not develop nuclear weapons and to allow inspections by the UNAEC to verify compliance, with punishments for violation of the agreement.
