From the Economist: Frustrated by European equivocation, Turkey is reversing years of antagonism with its Arab neighbours…

Turkey’s prime minister, Recep Tayyip Erdogan, has just been warmly received in the Iranian capital, Tehran, a reflection of the realpolitik that has kept links open despite the Islamic Republic’s international isolation. Turkey requires no visas for Iranians, and Mr Erdogan, who has stressed Iran’s right to nuclear power for civil purposes, pointedly congratulated Iran’s president, Mahmoud Ahmadinejad, after his disputed election win in June…

This dogged diplomatic pragmatism has been ardently pursued by the foreign minister, Ahmet Davutoglu, an ebullient professor of international relations who had long advised Mr Erdogan before his appointment in May. Mr Davutoglu, who in a book described the Middle East as “Turkey’s strategic depth”, has called for a policy of “zero problems with neighbours”. Reflecting the mild, modernist Islamism of the Justice and Development party, known by its Turkish initials AK, which has ruled Turkey since 2002, the new policy seeks to use the soft power of trade, along with historical links, to project stability beyond Turkey’s frontiers. This marks a distinct shift in worldview. In the past Turkey tended to see itself as an eastern bulwark of the NATO alliance, whereas its Middle Eastern neighbours were viewed as threats to be contained…

Turkish officials, however, have been careful to explain that their renewed interest in the Muslim east does not mean a chill towards the West. Instead, they present Turkey as a useful bridge, a regional force for peace, and the model of a democracy that is compatible with Islam. Its Western allies have generally shared that view and have not opposed Turkey’s eastward shift. Yet such benign indifference could change, if Turkey’s prospects for joining the EU die, or if Turkey is seen as undermining attempts to pressure Iran. (graphic: Peter Schrank/Economist)
