Dh thinks Iran is wanting to concentrate on themselves now. That the change is already happening within. 3rd of population is in poverty, and poverty there is... Well poverty. That's embarrassing for them.
I think he is being bit optimistic, but it's posaible that losing proxies made them change course? Who knows.
His family are very much aware of who the rebels are but hope it will workout. Bit of "selfish" reasons in it too as the number of refugees affected locals significantly, not just economy in their country. The syrian refugees around have fucking tough lives (I could not get over some of what I saw for a while), but the amount of people made all prices jump so even locals have issues renting and affording food and now hope thay if Syrians can go back, prices will fall. Bad for the shitty landlords offering garages as rooms to families.... They are also now scrambilng around trying to find out whose lost, presumed dead, cousin was in Assad's prison for last 40+ years and was just released... Interesting times.
While Syrians in Lebanon's camps are reported to start moving back to Syria, his are not saying anything yet about it. They have massive camps near so will probably see movement when, if, it starts.
Re West and we shouldn't think everything is "the west". In laws all very much believe that meddling by the west caused lots of the regional issues incl ISIS etc (Irak war specifically). Unintended consequences.
Please note, this is not some political official opinion. This is what the in laws are telling us.
