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.
