Business Week mentions what may be the next diplomatic step in the UN: trying to get the General Assembly overrule the Security Council:
The General Assembly can overrule the Security Council through a mechanism known as Resolution 377, or Uniting for Peace. It was passed in 1950 during the Korean War to circumvent the Soviet Union blocking action to protect South Korea.
It requires a two-thirds majority in the General Assembly to override the Security Council and its veto-wielding members and can be used when the 15-member decision-making body “fails to exercise its primary responsibility for the maintenance of international peace and security.”
This could become a diplomatic battle similar to that about the recognition of Kosovo.
