ATHENS, GREECE - JANUARY 26:  Greece's newly appointed Prime Minister Alexis Tsipras poses after taking a secular oath at the Presidential Palace on January 26, 2015 in Athens, Greece. Alexis Tsipras was sworn in with a secular oath, rather than the traditional Greek Orthodox ceremony, becoming the youngest man to hold the post of Prime Minister in 150 years. The radical left party Syriza won the snap Greek general election and has asked the right-wing Independent Greek party to form a anti-austerity coalition.  (Photo by Milos Bicanski/Getty Images)
