All nation states are like that. They monopolise power and violence, and will defend that monopoly by sacrificing their citizens' lives if another state tries to infringe upon it.

I think it's clear that the interests of citizens and their state typically do not align. Unfortunately, most states have cultivated and propagated a different idea for decades, which is why so many people have a different perception of their state than the reality.

No idea why you single out nation states, all states are similar.
