Without violence the state could not exist. This is not an opinion. Just think about it. If you take away war, forced currency control, and forced participation in state affairs, states as they exist today, simply could not be. They would not be able to reach the magnitude they have.

Historically, violence is exactly how countries came to be. One man or group of men claimed they magically owned vast swathes of land, declared themselves leaders or rulers, and use meviolence against anyone in their way, peaceful or not, to take control of a secure dominance of their particular region.
