What may have happened if the Coalition powers after Waterloo had decided to punish or cut down France instead of restoring French territory (and indeed letting them keep some of their annexed territory)? What territories may have been removed from France? How would this further have altered relations between the Coalition members (especially since there were some serious tensions between some of them)?
Were there any people present at negotiations who were in favor of weakening or dismantling France?
The British I believe were definitely in favour of crippling France.
Dismantling is out of the question, not only does it just not fly, but it's damn near impossible. France doesn't want to break, and they can't force that; even with Napoleon defeated, France can still wage war maybe not effectively but she's not going to down easy. France will be dragged down kicking and screaming before they get butchered by the Regional Powers.
Sure, the conquests can be lopped off, there's no maintaining those, but core France isn't something they'll go for. Should they actually attempt to break apart France, war will happen again and Europe will once more band together to fight the giant but afterwards once France is
truly exhausted and beaten, they may just try peace. Or they'll immediately start taking advantage of each other, I don't know I'm not a scientist.
