There will be an event in my town soonish about the background of the Ukraine conflict, and the speaker is a total lib. What questions should I ask, what incontrovertible facts can I use to combat liberalism?

I have Victoria Nuland and John McCain speaking and handing out cookies on the Maidan and talking about their material support for the coup. The revelations were used by western press but they came from Wikileaks and I can totally see that being dismissed out of hand. They'll probably also obfuscate the Nazi elements in a similar manner to the way the western press is doing constantly.

I have the UN/OSCE reports on civilian casualties in Donbas, I have the Congressional arguments about whether or not they want to support the Nazis directly... What else?
