The US and Turkey can agree all they like and it won't make a damned bit of difference. The Kurds, Syrians and Russia get a vote.
In the meantime, we are all free to question and condemn any and all politicians involved. IOW, business as usual. Let all the previous hatreds and preconceived notions flow through us.
Trump's fault. Obastard's fault. Bush's Fault (both), Reagan's fault, Carter's fault, Netanyahu's fault, Merkel's fault, Boris Johnspn's fault, Queen Maxima's fault. Mandela's fault. Al Sharpton's fault. Lydon LaRouche's fault. George McGovern's fault. Everett Dirkson's fault.
Just pick somebody and blame the shit out of them.
They're all wrong. It's MY fault. Send me a bill.
