Sure, many generals who didn't start the wars they fought.

This is a misunderstanding of the situation. Napoleon largely “started” his wars because the rest of monarchical Europe was conspiring to have him removed.

Conspiring? Other monarchies basically went to war to stop the French revolution so before Napoleon was even known (Napoleon got known through his victory in the "siege de Toulon" https://en.wikipedia.org/wiki/Siege_of_Toulon )

Yes, of course I’m oversimplifying it. The greater point being that Napoleon didn’t start the series of wars as a conquerer, which is how he is often portrayed (especially in English language history.)

The French revolutionary regime started the wars and literally expend in all direction and were absorbing country after county.

Instead of negotiation an end to war they attempted to take much of Europe and Napoleon continued that.

Peace was temporary and only as long as you followed what Napoleon wanted.

Russia tried peace with Napoleon but they realized that Napoleon only accepted piece if he was in control and could dedicated all policies they should. Once they didn't he invaded.
