I dislike all comparisons to WW2 events and leaders because they rarely work other than as leftist propaganda. However, you cannot deny that the annexation of Crimea is spot-on Sudetenland and the Austrian Anschluss.
I mention Mussolini, because until he began to try to create his North African Empire. he was still considered respectable, He had even made up with the pope after Italy and the papacy had been at odds for sixty years.
