KIEV, Ukraine As freshly sworn-in U.S. President Donald Trump constructed his inauguration address in Washington, he promised to break with the foreign policy of outgoing President obama. Nowhere is the threatening ambiguity of that promise being felt more acutely than in Ukraine, which was a priority of the Obama administration and which continues to fight a proxy war with Russia in the east of the country that by conservative estimations has claimed some 10, 000 lives.

During his last week in office former Vice President Joe Biden was in Ukraines capital city Kiev to meet with Ukrainian President Petro Poroshenko for his fifth trip to the country since the Maidan protests that ousted pro-Russian President Viktor Yanukovych. Throughout his tenure at the White House, Biden played the unofficial role of the administrations special envoy to Ukraine, and since the 2016 election, has worked to instill Ukraines importance on the new administration. Asked if he thought his efforts were successful, Biden answered only that hope spring eternal.

Nowhere is the threatening ambiguity of ‘America First' being felt more acutely than in Ukraine.

Ukrainians are concerned about Trumps focus on his relationship with President vladimir putin and that relationships potential to halt U.S. support for Ukraine. On the campaign trail Trump regularly praised Putin, and according to American intelligence and law enforcement officials, U.S. examiners are currently in the process of looking into contact between Trumps national security consultant and a top Russian diplomat.

Trump also recently said that he would be willing to remove imposing sanctions on Russia if the Kremlin agreed to a reciprocal reduction in nuclear arms, breaking with the previous administrations position that removing sections be linked to ending Russian military involvement in Ukraine that international sanctions were originally enforced over.Kiev reacted to this proposition in an interview after Trumps inauguration, recommending the new leader not to remove imposing sanctions on Moscow.

Trumps praise of Putin has led Russias elite to publicly hope for warmer relations under Trumps presidency, with multiple inauguration parties being thrown in the Russian capital. Ukrainians meanwhile fret Trump could relegate them to Russias sphere of influence, denying the countrys Western aspirations.

Ukrainian society has long feared that the West could sell out Ukraine by forcing a bad peace. In 2014, Ukrainian social media accounts launched a campaign against German Chancellor Angela Merkel after perceiving her to be too close to Putin, labeling her Frau Ribbentrop after the Nazi foreign minister, Joachim von Ribbentrop, who negotiated the partitioning of Eastern Europe between Nazi Germany and the Soviet Union. With Trump, those fears have surfaced again.
