Boris Johnson's only been foreign secretary for barely a day and now this? I hope it wasn't his poem that pushed them over the edge!
Seriously. The implications as regards ISIS are trivial compared with the fact Turkey is a member of NATO and occupies an awkward position in the emerging new Cold War between Russia and the West.
If things go bad in Turkey it's not inconceivable Russia may want to move in troops. And the US would not stand for that.
That's what to worry about here.
