I concede that I never considered how they are not hospitable to Syrian refugees, however I think it is debatable that Russia instigated this turn of events.
From my perspective, if Saudi and US influence was not pressed in support of rebels in Syria, then this rebellion would have been crushed a long time ago. There would not be a war, there would not be refugees right now. Yes the people of Syria would not be free but lives and families would not be lost.
The fighting is only as drawn out and brutal as it is because of Saudi and US intervention.
