Didn't the USA back a coup in the Ukraine when you were president, Mr Obama? In 2014? Don't you think that's also a threat to Ukraine's "sovereignty, self-determination and democracy"?
I'm not equating that with what Russia is doing (they're much more violent), but I am wondering about the hypocrisy of the statement that Russia is attacking the Ukraine "because they chose a path of sovereignty, self-determination and democracy". When the US under your presidency meddled with the Ukraine's sovereignty and self determination?
