Though the five original members might agree to enlarging the permanent membership to more realistically represent today’s world, they are unlikely to extend to newcomers the rite of veto bestowed on them at the time of the UN’s creation. When all the politicking and jousting is over, enlargement of the Security Council would have to be approved unanimously by the five original members, and by two-thirds of the UN membership, let alone the US Senate.
Origins of the Security Council
The UN was born in 1945, a creation of Britain, France, the US, China, and the Soviet Union, who saw themselves as guardians of the post-World War II peace, with dominance of the new international entity. Beyond the Security Council’s five permanent, veto-bearing nations, there are 10 elected, nonpermanent members with two-year terms.
