How It Happened: Putin’s Invasion Part V: The Fight for the Donbas goes straight to the frontlines of the war, seen through the eyes of a journalist who has been covering the war there and a soldier who has been fighting there, both since 2014.  After the failed effort to take Kyiv, Russian President Vladimir Putin turned his focus to the Donbas, vowing to "liberate" the entire region, which was partially controlled by pro-Russian separatists before he launched his full-scale invasion on Feb. 24.  Ukrainian President Volodymyr Zelensky has described soldiers in the Donbas as some of the best Ukraine has. Their battle to defend this region will decide the fate of the war. Axios World editor Dave Lawler spent weeks interviewing Ukrainian Cpl. Andrii Shadrin and news producer Kateryna Malofieieva to understand the region’s history and significance, the realities of daily life on the ground, and why the stakes of this fight are so high.  Credits: This episode was reported and produced by Dave Lawler and Naomi Shavin.
