I believe the American Revolutions stopped at the correct point while French ultimately went to the wrong direction with Robespierre, the Reign of Terror and extreme anti-clericalism. This doesn't, however, change the fact that the ideological origins of both initial revolutions have a lot in common.
Some of the speakers on the show made collegiate type of comments such as (paraphrase) "In revolutions you need to kill the king" or "Revolutions need blood". Although America's revolution did spill blood, we did not feel we had to kill King George III. History shows that the less bloddy the revolution, the easier the transition.
