The ceasefire due to come into force on Sunday, barring a major last-minute problem, will cement massive and rapid changes across the Middle East and may seal a significant defeat for the Islamist militant groups that have been powerful actors in the region for years.
Hamas in Gaza, Hezbollah in Lebanon and assorted Shia Muslim militia in Iraq and Syria will all emerge from the conflict considerably weakened. Only the Houthis in Yemen are stronger – though this may not last. The Islamic State remains a shadow of its former self.
