>There are no good or evil regional powers, only national interests and the smaller nations which either get in the way of those, or help you achieve them.

Be that as it may, it still matters how the people in power think and behave. Some systems of government are better suited to reduce violence than others. For example, a dictator is probably more likely to order military intervention than a person who has to justify their actions to advisors, a congress and eventually a whole nation.

Obviously as you say things get murky when there are large interests at stake and no side is wholly good or wholly evil, but still some can be more wrong than others.
