[Editor’s Note: If nothing else, at least listen to the first 25 minutes of this interview with Professor John Mearsheimer, in which he explains the most important context for the Ukraine crisis. He emphasizes that no one was accusing Putin of expansionist ambitions before February 22nd of 2014, the date on which a US-influenced coup occurred in Ukraine, replacing a pro-Russian leader with a pro-American leader. Mearsheimer shows clearly how the folly of NATO expansion is at the root of the crisis.]
