In every military conflict in the history of warfare, combatants have taken steps to inspire fear in their adversaries. You may be providing a definition of terrorism, but I don't think it's a useful one; I think you need to refine it more if you want to make it operable here.
In any case, where you use the word "fear" I would probably use "deterrence".
