Obama wants to dray NATO into the war so he will have an excuse to support ISIS.
Nasty, but plausible. The bind is, Obama can't support ISIS without opposing Putin, his Communist seigneur. ("More flexibility", remember?)
Russia and Turkey are at loggerheads, but the real question is, who is on whose side? Can ISIS, or Russia for that matter, be on two sides at once? I'm satisfied from what I've read in FR that Obama is dogging it versus ISIS/ISIL/Daesh and is suspiciously seemingly sympathetic to the jihadis.
The American veterans are voting with their feet and reporting to Peshmerga units for service against ISIS.
