Hafez al-Assad was the 18th president of Syria from 1971 until he died in 2000. He was the number one regional enemy of Türkiye. Starting in the mid-1980s, Syria provided the PKK and its leader Ocalan with safe havens from where they launched terrorist attacks against Türkiye across the 910-kilometer border. President Assad, despite irrefutable evidence provided by Ankara over the years, constantly denied support. Türkiye’s patience finally ran out. In the fall of 1988, the Turkish land forces commander delivered an ultimatum on the border saying that either Syria deported Ocalan or the Turkish army would move in. Hafez al-Assad complied. On October 20, 1988, Türkiye and Syria signed the Adana Agreement which was essentially a commitment by Damascus to end its support to terrorism.
