It is hard to credit now, but there was a time, only a decade ago, when Turkey described its foreign policy doctrine as one of “zero problems with our neighbors.”  But since then, Ankara has burned its boats with Israel over the Gaza Freedom Flotilla; angered Egypt by bitterly criticizing Gen.

Now, Turkey is providing direct military assistance to the government of Libya, while the UAE and Egypt—along with Russia—back the rebel army of General Khalifa Haftar. After the failure of cease-fire talks sponsored by Turkey and Russia, President Recep Tayyip Erdogan promised to teach Haftar “a lesson.”
