A close ally is abandoned, and Isis is regrouping. The speed of the unravelling is breathtaking
In the week since Donald Trumps fateful phone conversation with Recep Tayyip Erdoan, the US has entirely abandoned the Kurds, its most effective allies in the Middle East, and with them a Syria strategy that was five years in the making.
The Islamic State flag has been raised once more and the last vestige of US credibility as a reliable partner lies crushed under Turkish tank tracks. It has arguably been the worst seven days for US foreign policy since the invasion of Iraq.
Administration officials have been under orders to deny that Trump gave Erdoan a green light to invade north-eastern Syria, despite all the indications to the contrary. After the Turkish leader announced his intention to invade, Trump invited him to the White House, one of the most coveted rewards a US president can bestow. And even as his aides are instructed to lie on his behalf, Trump continues to flash a green light on Twitter, and not just to the Turks.
While echoing Turkeys view of the Kurds as terrorists, Trump declared: Others may want to come in and fight for one side or the other. Let them!
