After all, only five countries are permament members, and only they have individual vetoes to block any decision they don't like. The five, broadly the first nuclear powers, are the United States, Russia, China, Britain and France. Other countries have temporary membership of the Security Council on a rotating basis.

But it is hard to see radical change being agreed quickly.

The United Nations was established by 51 countries in 1945, in response to the horrors of the Second World War, and the political failures which failed to prevent it. When the UN was born, the world's total population was 2.5 billion. The task of finding ways to put an end to that scourge is as vital today as it was in 1945.
