When Germany invaded Europe all the male refugees that made it to England wanted to do was to train to be a force to take their country's back. Given that 80% of Syrian refugees were men of fighting age it's interesting that none of them seem to want to train as a force to get their country back. If they aren't why the hell should any other armed force lay their lives on the line. Leave it to Assad and his Russian friends who are based in the sovereign country, we already have our hands full in other missions in the area.
