It sounds like hyperbole—unless you listen to the Russian president's thinly veiled threat to use nuclear weapons on any country that intervenes with his aggression in Ukraine. That doesn't mean this conflict will escalate to a multi-nation war, but the possibility is certainly there, according to experts. And nobody knows what happens next.What does this mean for the future of the international order and traditional alliances? What does it mean for millions of innocent Ukrainians? For countries like Canada who are on the sidelines? How will this conflict reshape the world in the weeks and months to come?GUEST: Balkan Devlen, senior fellow at McDonald Laurier Institute, Superforecaster for Good Judgment, Inc.
