True, but at some point it becomes time to grab some people, firmly, by the shoulder and walk them to a place for poking holes in them to let the go-juice out.
The idea war and air war are all in support of that necessary strategic play to compel surrender.
Wars end when the other side fails their agenda and seeks diplomatic resolution or when that side achieves its objectives.

One of those two things must be corrected in the end, and depending upon who they are or what their ambitions may be, they may be required to have their life returned to the hereafter in order to prevent them from ever doing it again.
