Any North Korean invasion would be weakened by 4.7 million new conscripts

Were they to receive 4.7 million new volunteers, the North Korean armed forces would be less able to fulfill its overriding war objective: the forcible reunification of North and South Korea.

This is relevant, in that North Korean state propaganda announced on Thursday, that 4.7 million of its citizens have now volunteered to join the military. North Korea intends for this volunteer pledge to intimidate the U.S. and South Korea, and make the threat of war appear ever closer.
