As I right this, the time has been reached for a "cessation of hostilities" in Syria.
This is not the same as a cease fire, because, well, they wont be ceasing fire.
Some groups such as ISIS and Al Nusra will still be targeted by Assad. Previously, Assad and Russia have in the name of bombing ISIS bombed anyone but ISIS, so it will be worth noting what happens this time.
Other smaller groups may join the cessation of hostilities, or they may not depending on many things including whether they themselves are bombed and targetted.
I don't think that anyone really expects much to be accomplished here, but even an unfair cessation of hostilities is better than nothing because atleast the people will have some peace - if it works out.
The Assad regime has killed many people, tortured many more and there will be many that will be seething with a result where they see that his regime has gotten away with their crimes.
Others will be frustrated that they were not able to remove a regime allied to Iran (and now more importantly, Russia).
Turkey will be worried about the YPG Militia which it claims has ties to the PKK in Turkey.
But sometimes the best result may be one where no one is happy.
Let the people live and justice will be served at a later date (and maybe not in this world).
