Apparently, Turkey is sending a thousand troops to that Turkish/Greek border in order to prevent the Greeks from keeping their border secure, with the migrants still within Turkey.
With little love lost between those two counties, this could erupt into a mini-war of its own.
One must sympathise with Turkey, nonetheless. It is holding millions of refugees already, and its own people are sick of it, as are the Greek islanders facing the same situation.
The brutal reality is that nobody wants these people. All those pretty international agreements, resolves and moral highgrounds are cool when there is no existing situation, but quickly vanish when reality comes streaming down the country road. As ever, it's one of those problems that requires solution where it begins: at home.
