@Fash-E The french were the worse.
Literally the jewish hand on the whole WW1 plot , all of these "loose assassins" acted with a tight contact with the french who set up an entire network and had the intent of destabilizing the pre WW1 order.
Past that, the jews had simply to economically fuel and aid in this or that crisis , expecially knowing Russian Empire was on the brink, the Humbert I assassin for example trained in France after a period in the US.
The whole "anarchists pulling big scores" trope has always been historically laughable.
