According to Amir Tsarfati, an Israeli intel specialist, Israel actually likes the pullout because it give them greater freedom to deal with Iran and Syria. Erdogan claimed during the call that Turkey can finish off ISIS. Since Trump was looking to fulfill a campaign promise to get the troops out of the Middle East, He jumped on Erdogan’s offer. Erdogan was as shocked as anybody when trump accepted his offer. Also, Trump received multiple intel reports from different agencies that Kurds had worked a deal to sell gas and oil to Bashar Asaad. In fact, the Kurds are having official contact with Assaad and are willing to subject themselves to his sovereignty. They are now collaborating together. A new coalition has been formed. Shiits and Iran are included in this coalition group. When Trump realized that he was being deceived, he said enough was enough. These people hate us and are waisting American lives and money on them.
I saw that thread too. IMHO ISIS was all but defeated last year, and Trump was saying he wanted out in April. If the situation is so stable that the survivors/winners are negotiating terms on their own without the U.S., we really have no business keeping troops in the country.
