Sorry Ronald, but you don't laud a foreign invasion of a sovereign European country and annexation of swathes of its territory (not to mention the downing of a civilan airliner with the deaths of nearly 300 innocent people in the process - you seem to be strangely quiet on that), and then get to preach about 'legitimacy'.
I could say that Yanukovych was ousted by his own people in a popular uprising, who then replaced him with a new president in a democratic election, but I know I'd be wasting my breath, so to speak.
