(FILES) In this file photo taken on November 22, 2014, US Vice President Joe Biden (L) speaks with Turkish President Recep Tayyip Erdogan at Beylerbeyi Palace in Istanbul.  President Biden has opened his presidency by taking a visibly harder line on Turkey, with analysts expecting a rocky path ahead between the uneasy allies as their interests increasingly diverge. Erdogan, like many of the leaders who wooed Biden's predecessor Donald Trump, is getting an early cold shoulder from Biden, who before being elected described the Islamist-aligned populist an autocrat and promised to empower the opposition. / AFP / Bulent KILIC
