A Turkey as resurgent as at any time since its Ottoman glory is projecting influence through a turbulent Iraq, from the boomtowns of the north to the oil fields near southernmost Basra, in a show of power that illustrates its growing heft across an Arab world long suspicious of it. Turkeys influence is greater in northern Iraq and broader, though not deeper, than Irans in the rest of the country. While the United States invaded and occupied Iraq, losing more than 4,400 troops there, Turkey now exerts what may prove a more lasting legacy so-called soft power, the assertion of influence through culture, education and business. This is the trick we are very much welcome here, said Ali Riza Ozcoskun, who heads Turkeys consulate in Basra, one of four diplomatic posts it has in Iraq. Turkeys newfound influence here has played out along an axis that runs roughly from Zakho in the north to Basra, by way of the capital, Baghdad. For a country that once deemed the Kurdish region in northern Iraq an existential threat, Turkey has embarked on the beginning of what might be called a beautiful friendship.
