Abstract. The article analyzes the US policy towards Ukraine dating back from the time before the reunification of Crimea with Russia and up to Donald Trump  coming to power. The spectrum of Washington’s interests towards this country being of particular strategic interest to the United States are disclosed. It should be noted that since the disintegration of the Soviet Union Washington’s interest in this country on  the whole has not  been very much different from its stand on  all post-Soviet states whose significance was defined by the U,S  depending on  their location on the world map as well as  on the value of their  natural resources. However, after the reunification of Crimea with Russia Washington’s stand on this country underwent significant changes, causing a radical transformation of  the U,S attitude in their Ukrainian policy. During the presidency of Barack Obama the American policy towards Ukraine was carried out rather sluggishly being basically declarative in its nature. When   President D. Trump took his office Washington’s policy towards Ukraine became increasingly more offensive and was characterized by a rather proactive stance  not only because Ukraine became the principal arena of confrontation between the United States and the Russian Federation, but also because it became a part of the US domestic political context. Therefore, an outcome of the “battle” for Ukraine is currently very important for the United States in order to prove to the world its role of the main helmsman in the context of a diminishing US capability of maintaining their global superiority.
