Not sure the West is at the stage of accepting that Assad might have to stay at least short term
I am currently working in West Africa and have just returned from dinner with various Turkish and Lebanese business and diplomatic people - they were all adamant in blaming UK and France for the recent bombs in Lebanon because - according to them - UK, US and France are "supporting" IS because we are opposing Assad.
I think we are a step closer now to accepting that supporting Assad and Iran is the best solution to the crisis in Syria and Iraq.
