Ian Bremmer's Quick Take: Hi everybody. Ian Bremmer here, and a Quick Take to kick off your week. I have to talk about Russia. There's plenty of news in the world. There's Brazil, there's United Kingdom, there's Iran, but no, Russia is the biggest story, and it's because we've just seen the worst week in the war in terms of escalation and danger that we've had since the initial invasion on February 24th. President Putin, after meeting with some of his closest remaining friends on the global stage, the Indian prime minister, the Chinese president, the Kazakh president, all telling him directly, "Hey, the war is a horrible idea. Please end this as soon as possible." Putin does exactly the opposite and escalates. Calls up a minimum of 300,000 additional troops in a mobilization, something he had been dragging his feet on and avoiding over the last months because he knew how unpopular it would be in Russia.
