It's a fairly simple question. Common opinion on this board seems to be that Napoleon was just too ambitious to accept any peace but a victor's peace. History seems to bear that out, as the only time he was even willing to entertain the extremely generous "Frankfurt proposals" it was clear to anyone he couldn't stop the allies from marching in and imposing whatever peace they wanted. That in itself was a huge missed opportunity, as France entering the industrial era with the Rheinland and Belgium would have been massive boons.
So what would be the best point for Napoleon to die (via falling brick or brain aneurysm) to preserve's France's ascendant position? After Tilsit? Borodino? On Elba? Or perhaps earlier, after Amiens and before the coronation, leaving France a republican dictatorship under Cambaceres and Lebrun, at peace with Britain?
Myself, I lean towards the latter position, but I'm interested in the opinions of others.
