In part two of How it Happened: Putin's Invasion, Axios world editor Dave Lawler explains how Russian President Vladimir Putin's decision to invade Ukraine catalyzed a chain of events that are reshaping our world. Lawler is joined by Axios managing editor Margaret Talev to discuss President Biden's decades of political experience with Russia and the sanctions the U.S. and Europe have brought against the country. Energy and climate reporter Andrew Freedman explains why it's so hard for the West to cut ties with Russia when it comes to energy, and why the Biden administration chose to do so even if it would send gas prices soaring.
