Alexander Kamyshin is in charge of arming Ukraine's defense industries, and gathering military hardware from allies to sustain the country's defense against a Russian invasion. This week he is in the American capital meeting with lawmakers and business leaders alongside his Defense Minister Rustem Umerov and President Volodymyr Zelensky. He was the guy who led Ukrainian railways and went viral for his success at keeping the country's train network running punctually during the early days of the war. He managed to not only deliver millions of Ukrainians safely, but also transport the leaders of the free world in and out of Kyiv. One Decision's Sir Richard Dearlove met Kamyshin in Ukraine earlier this year and joins with his thoughts on the logistical leader’s efforts and the state of his supply chain.
