There was a time not all that long ago when the United States would be seeking clearly to drive and define a particular narrative and outcome for the events unfolding in the Middle East.
Seeking to mould events to its own benefit has been a central tenet of American foreign policy.
But the remarkable and fast-moving developments in Syria, come at an unusual moment for America.
Syria latest: Rebels expand control
In Washington DC, there is a vacuum of leadership.
We are in the midst of the transition between President Joe Biden and president-elect Donald Trump.
President Biden is still running things at the White House but his ability to influence events in the Middle East, if he is even inclined to, has been shown to be limited. He is the lamest of lame duck presidents.

Insurgents close in on Homs
Mr Trump will not take over as president for another six weeks. And yet already it feels like he is more of a player and moulder of global events (because of what he does and doesn’t choose to do and say) than at any time in his last presidency.
There’s another difference this time too.
During Mr Trump’s last presidency, there were powerful European counterbalances. But now, Germany’s former chancellor Angela Merkel is long gone and Mr Macron is weak, despite his diplomatic masterstroke in inviting Mr Trump to Paris.
