At the end of the day you can always have a revolution.

Political solutions are always possible, given the will.

Which didn't work out so well for France in the 1790s. Well not for the aristocracy anyhow.

Their politics changed, but it was an exceedingly messy process.

In the same century it worked ok for the overseas colonies.

I don't see the revolution of 1790 as going wrong, although it laid out the process for the first total war in Europe.

Revolutions are the extreme political actions, they should be left for when all else fails.
