IMO, it was one of Nap's biggest blunders.
hurt France more than Britain.
hurt other countries so much that they would never be more than a token ally to France.
Didn't hurt Britain enough to back down.
It may have seemed like a good idea at the time, but ultimately, it was almost all bad, and very little good.
Portugal/Spain iberian war was a direct result, as was Russia.
Alt world, Nap should have never gone down that road.
if you want to change the Nap wars, CS is a prime candidate for changing.
