The Paris mob.
In business since 1787
The French Revolution wasn’t an organized uprising but events in several locales spiraling out of control.
If the current melee spreads beyond Paris, then the government and perhaps the Fifth Republic will topple. Macron has no young Napoleon to scatter the rioters with a whiff of grapeshot and if he brings in the army then it’s civil war.
And there is no Charles de Gaulle to march in and assume power.
