In October 2019, after Erdoğan spoke to him, U.S. President Donald Trump gave the go-ahead to the 2019 Turkish offensive into north-eastern Syria, despite recently agreeing to a Northern Syria Buffer Zone. U.S. troops in northern Syria were withdrawn from the border to avoid interference with the Turkish operation. After the U.S. pullout, Turkey proceeded to attack the Autonomous Administration of North and East Syria. Rejecting criticism of the invasion, Erdoğan claimed that NATO and European Union countries "sided with terrorists, and all of them attacked us".
