After hearing Turkish President Recep Tayyip Erdogan threaten for two years to launch an assault against the Kurds in Syria, President Trump and senior administration officials did not think he would ever go through with it, six people with knowledge of the matter told Axios' Jonathan Swan.

Their discussions started in 2017, with Erdogan telling Trump the Kurds, who control northeastern Syria, are a threat to Turkey and need to be away from the border. Whenever he would say this, Axios reports, Trump would let Erdogan know that if he did invade, he would have to be solely responsible for whatever happened. During one conversation, Trump conveyed that Erdogan shouldn't mess with U.S. troops in Syria, but intimated that they wouldn't be there much longer and would not stay around to help the Kurds, people with knowledge of the matter told Axios.

Usually, Erdogan would take a few steps back, but last Sunday, he told Trump the invasion was on. Trump soon announced that U.S. troops would be pulled back from the border, a move that sparked bipartisan outrage, with lawmakers blasting Trump for turning on the United States' Kurdish allies. Erdogan thought Trump would reel him in, Turkish sources told Swan, and now he is in over his head as he faces international condemnation. Read more at Axios. Catherine Garcia
