A top Russian spook, Maksim Filchenkov, has been living in Tokyo disguised as an executive of Aeroflot. He has developed relationships with mid-sized logistics companies and persuades them to supply illicit technology, flown to third countries such as Sri Lanka or Vietnam. Aeroflot, then charters one of its planes to collect the goods and get them to Moscow. It’s ruthlessly efficiency: Ukraine estimates that as much as 90% of Russian weapons, drones and missiles contain Japanese components.
