Are you implying that the Napoleonic wars, all of the resulting politics, etc. are the natural result of revolution? That the revolutionary ideal requires military defeat in order to reach a positive end state?

You're not being serious if you end there.

The question is if these ideas, already in place would have come to fruition without the suffering of people up front. We just can't know. I remember a similar discussion with my history professor and us students when talking about the French Revolution and about the Enlightenment. We basically have only one history and are not able to state that the French Revolution was the cause for these good ideas to follow. We couldn't even state it as a catalyst with certainty.
