Answer:
Similarity--both the US and France went through periods of adjustment on their way to a permanent government.
Difference--the US was able to create a democratic government and make changes from the Articles of Confederation to the Constitution without a complete revolution and extreme violence. France on the other hand established a tyrannical government and then a dictatorship under the rule of Napoleon. It took more time and stages for France to find a democratic balance they were hoping for.
