To Lt. Gen. Vincent R. Stewart, USMC, director, Defense Intelligence Agency (DIA), modern warfare is a cognitive battle. To be successful, warfare must strive to control information.
In part, war is still a violent clash between hostile forces, with each force trying to impose their will on the other, the general said. Warfighting may still look like two armies crashing into one another on the battlefield.
“[This] nature of warfare hasn’t changed,” he stated. “War remains an active force to compel an adversary, nothing less.”
