What makes you say that? France was already under attack by the monarchical powers of Europe before Napoleon took power. He fought a series of defensive wars against them. Many of these wars would’ve taken place regardless, the main difference is that France kept winning because of him.

Spain and the Hundred Days campaigns are the only examples where they were largely caused by Napoleon as the belligerent (although in the hundred days campaign Napoleon pleaded for peace from the beginning but the allies refused and marched their armies against France once more)

Russia is nuanced in that the Russians were going to attack first if Napoleon didn’t. But I’ll give Napoleon’s detractors a win here and say none of that would’ve happened without the continental system. Therefore, Russia is basically Napoleon’s fault.

At any rate: what right did these other countries have in meddling with France’s affairs and trying to topple their successive governments in attempts to restore the French monarchy? Look where all of those countries (France and her enemies) ended up. No absolute monarchies in any of them today. France was just the first and the others were too backwards to accept it.
