If Donald Trump is looking for practical advice on how to fulfil his controversial pledge to build a wall along the U.S.-Mexico border, he may want to ask Turkey for help.
Facing increasing spillover from the war in neighboring Syria, Bulent Arınç, Turkey's deputy prime minister, announced in July 2015 that the NATO member state would build a wall along its entire border with Syria. Sections already existed in some areas, but this plan would cover the entire 911-kilometer border. Work is entering the final stages, with roughly two-thirds of the projected completed.
