Just war

The base of war, is a fight over resources.

If individuals can find a way to divide resources in a peaceful manner, it is ok. If they can't then war will result, when one side ot more, will use force to take their share, or all resources.

The role of the government is to find ways to handle resources peacefully.

If some think that the government do not handle resource in a just way, they may try to change it through political means.

If she can not influence the government to change it's way to a more just handling, the government may be considered her enemy, and she will be the enemy of the government.

Usually, to deliberate and find just solutions in the government, there should be a common culture, therefore different cultures have trouble leaving in the same state. The deprived will be the enemy of the majority.
