The massive corruption probe that has left Prime Minister Recep Tayyip Erdogan with the most damaging crisis of his political career has started to spill over into Ankara’s relations with Washington. A crisis between the two countries has been averted for now, following intense diplomatic contacts, but Western diplomats have confirmed to Al-Monitor that patience with Erdogan is running thin on the American side, where officials are threatening dire consequences to relations should he continue in this vein.

Never the one for diplomatic niceties or sensitivities when it comes to politicking, Erdogan has latched on to reports in Turkey targeting US Ambassador Francis J. Ricciardone Jr. in connection with the current probe. After accusing the ambassador, without naming him, of engaging in “provocative actions,” Erdogan even threatened to send him packing. Erdogan’s attack followed an orchestrated and concerted assault on the ambassador by pro-government media trying to deflect attention from the government after news of the corruption scandal hit the headlines on Dec. 17. Days later, on Dec. 21, Aksam, Star and Yeni Safak accused Washington, in large print, of being behind the probe that has left four government ministers under suspicion.

Washington was said to be angry with Turkey for circumventing sanctions on Iran by buying oil from Tehran and paying in gold cleared through the government-owned Halk Bank. The CEO of the bank has been arrested for taking bribes and is facing a trial after millions of dollars were found in shoeboxes in his home.

According to the papers above, Ricciardone told the EU ambassador in Ankara the day the scandal broke that Washington had warned Turkey to cut its ties with Iran. “They did not listen to us. You will now watch the fall of the empire,” Ricciardone allegedly said.
