In part three of How It Happened: Putin’s Invasion, Axios World editor Dave Lawler examines a difficult reality — that the only clear path to peace in Ukraine is a deal between Russian President Vladimir Putin and Ukrainian President Volodymyr Zelensky, but the red lines drawn by the Russian and Ukrainian leaders do not intersect. This episode features interviews with Zelensky’s chief of staff, a member of Parliament in his party, two close observers of Putin and the Kremlin, and a former U.S. ambassador to Ukraine with decades of diplomatic experience in the region.  Across these interviews, Lawler tries to determine the end games for Putin and Zelensky and the likeliest scenarios for how this conflict could end.  Credits: This episode of Putin's Invasion was reported by Dave Lawler in collaboration with the Axios newsroom and produced by Naomi Shavin.
