We think it is high, very high. After all, Russia has already annexed the whole of the Crimean peninsula without a real fight. Why won’t she annex other pro-Russian regions too, especially the eastern oblasts of Ukraine? Like Adolf Hitler after the 1938 Munich Conference (remember “peace in our time”?), Russian president Vladimir Putin now knows he can treat his neighbors with utter impunity, for Ukraine’s fair-weather and feckle allies are not willing to back up their empty rhetoric in defense of Ukraine’s territorial integrity with any military force (not even with the threat of force). In sum, why haven’t we learned the lessons of history? (By the way, isn’t it time for our friend Edward Snowden to man up and speak out against Russia’s aggression? Or is Mr Snowden, in effect, a hostage of President Putin?)
