 Tarkin's concept was that rule could be established and maintained "through fear of force rather than force itself", and he believed grand display of power could suppress dissent and rebellion into submission.This Doctrine became the Empire's core military doctrine of peacekeeping, internal security, counter-insurgency, and state terrorism-philosophy.The instrument of this power is the military, which includes the Imperial Stormtroopers, a massive fleet of 25,000 Star Destroyers, 50 Super Star Destroyers, and the Death Star, a moon-sized superweapon capable of destroying entire planets.
