Around the time of World War II, Marshal of the Soviet Union Y. N. Shaposhnikov explained, "Mobilization is war, in our minds there is no other meaning for it." Having recalled many of its people from Russia and China, it appears that some kind of mobilization has been underway in North Korea. Small moves, like placing artillery units in north-facing caves and increasing the number of divisions on the border with South Korea, indicates something more than the usual bluster.
