The passage of a UN Security Council Resolution in New York is a very big deal.
The Syrian conflict is nearly 1,000 days old and 100,000 people have been killed but up to now the Security Council has done nothing.
Not only might a resolution eliminate the Syrian chemical weapons stockpile, but it could also suggest that Russia is moving from being an obstructionist force to being a cooperative player.
I ran into a Middle Eastern ambassador earlier who said if this all goes wrong, America will emerge looking terribly weak, having been outmanoeuvred by Russia and Syria.
But he added, half jokingly, if it goes right then president Obama will deserve a second Nobel Peace Price.
