The quickest way to kill the Eighth Coalition is to stop the war. Once the war's over, so is the Coalition. You fundamentally misunderstand the nature of a coalition; the Eighth is not a permanent military alliance. Once the war is over, it simply ceases to exist.

Heh, this a good point. The only reason there is a coalition is because you are prolonging their need to exist by dragging the war along. The Coalition members might have gone back to competing against each other by now had you surrendered along with everyone else.
