The close relationship between U.S. President Donald Trump and Turkish President Recep Tayyip Erdogan has brought the countries closer to resolving issues that led to Turkey being kicked off the F-35 fighter jet program, the United States ambassador to Ankara said Wednesday. “The positive relationship between President Trump and President Erdogan has created a new atmosphere of cooperation, which has led to the most fruitful conversations we have had on this topic in nearly a decade,” Ambassador Tom Barrack wrote in a social media post.
