A lot of people despite the idea of killing, but as technology advances, and the cost of weapon systems increases, it is less and less likely that these expensive systems will be used to target innocent people, since doing so is likely a waste of resources. On the other hand, usually it is those less-advanced weapons that inflects most mass casualties.
Some country can perform a successful head hunt in the span of an afternoon tea party, while some other country have to level cities for few years and yet still fails to even touch the opposition leader. That's the difference between advanced and less-advanced systems.
If people here loves peace, good. But if we can always reasoning our way out of conflict, then why do we also invented the career of professional police force?
Of course, it is possible that countries advanced too far ahead might bully those less-advanced ones. But then, maybe the less-advanced countries should look inward and reflect on the question why can't they themselves create such advanced weaponries. I don't know, maybe these countries instead of forcing their own people to wear an obeisant smelling face mask, it's time to gave back the power and opportunities so their people can actually grow and gain and eventually contribute.
