Out of all the wars to get involved in THIS was the most deserving and we did absolutely nothing. Its seemingly increasingly likely to we will end up at war with Syria and I wouldnt be surprised if DT has regular troops on the ground there within a year, since there is already several marine Battalions there helping out the Iraqi forces it shouldn't exactly be difficult to pass through. I also wouldnt be surprised to see Russia flip on the issue, if the US gives them enough benefits.
As for ISIS, The Iraqi army are sorting them out , the YPG are of course helping and made amazing ground a few years back but them getting battered by Turkey (bc **** Turkey) isn't exactly helping as they can seriously move turf when they are not getting shelled by a wannabe EU member..
