There is nothing particularly profound or revelatory in this article but it's worth considering and filing away. The issue of resources and the Russian Far East have come up before in history. There were those in Imperial Japan who coveted these lands and had an opportunity to invade from their colony of Manchukuo (the conquered realms of Manchuria) in the 1930's. In fact after the German invasion of the USSR in June of 1941, Stalin hesitated to bring the desperately needed troops from Siberia to the West, as he believed the Japanese would invade - something Berlin was very keen for them to do.
