The Turkish Government's policy of "zero problems with neighbours" is in need of urgent recalculation as neighbourly relations give way to threats from Ankara on several fronts.
Besides turning its wrath on Israel - not a neighbour but a former close ally - it warned Cyprus last month it would take "appropriate action" if Nicosia pursued its plan to undertake oil and gas exploration in the Mediterranean.
Such an undertaking, said Ankara, ignored the rights of the Turkish part of the divided island. This drew a quick response from Cyprus' patron, Greece, which said it not only stood behind Cyprus but that it would undertake oil exploration itself in disputed waters of the Aegean Sea despite Turkey's long-standing objection.
Foreign Minister Ahmet Davutoglu, formulator of the "zero problems" policy, warned another neighbour, Syria, last month to halt its violent suppression of demonstrators immediately. Otherwise, he said, "there would be nothing more to discuss about steps that would be taken". There have been unofficial hints from Turkey these steps could include military action.
A resumption of violence by the outlawed Kurdistan Workers Party (PKK) on Turkey's southeast border has brought renewed Turkish air strikes against PKK camps in northern Iraq after a relatively long period of calm. There is concern in Baghdad that Turkey might try to repeat its 2008 ground incursion into northern Iraq.
