Is that why? Wars tend to be fought, ostensibly at least, in the principle that fighting them ends/ruins fewer lives than not fighting them, and at least in many cases for the purpose of resource acquisition. In any case, the mere fact that wars are sometimes fought does not begin to imply they're actually a good idea. So if you want to prove some ideas are more important than lives, rather than just that some people with power think so: try harder.
