preemptive strike

In every war the salarians have fought, they struck first and without warning. For the salarians, to know an enemy plans to attack and to let it happen is folly. To announce their own plans to attack is insanity. They find the human moral concepts of "do not fire until fired upon" and "declare a war before prosecuting it" incredibly naive. In defensive wars, they execute devastating preemptive strikes hours before the enemy's own attacks.
