Could you go back an re-read what I actually wrote, please? The UN does not have the legal authority to:
- create international borders between States
- create States
- dissolve States
You should reread my reply to you
It is FOREMOST the UNSC that decides upon a resolution that also defines territorial borders - if the UNSC would have acknowledged Putin's annexation of Crimea, logically the borders need to be redefined.
If the UNSC does not acknowledge Israels illegal annexation of the Golan Heights - they need to be returned to Syria - aka Israels self-proclaimed border will change.
If Israel refuses to acknowledge such a decision/resolution by the UNSC - the UNSC can place embargoes and sanctions onto Israel - right down to sending a UN Peacekeeper-force to enforce it even militarily against Israel.
Who do you think drew/decided the
borders of the former Yugoslav States, AND ENFORCED them via e.g, KFOR towards Serbia? or in regards to the United Nations Mission in Bosnia and Herzegovina (UNMIBH), a peacekeeping mission set up by the UN Security Council in December 1995. It was under the UNSC that Bosnia, Herzogovina arranged and agreed upon
the future border with Serbia and other neighbor-states.
The UNSC is foremost tasked to ensure INTERNATIONAL LAW - the annexation of the Golan-Heights by Israel is in breach with international law - aka the self-declared border of Israel is in breach with international law.
And nowhere did I state that the UNSC creates States or dissolves States.
However - without a UNSC resolution, there wouldn't be a sovereign country called South-Sudan.
