Robespierre was a joke. The humanist Left fixed his wagon.
Correct ... he was a maniac. But one man can head a revolution, but it takes many "helpers" to make it happen. It took Napoleon to sort things out. In a manner of speaking, it took Stalin to sort out the mess that Lenin had made. Hitler sorted out the mess that the Weimar politicians made. When things get darkest, break the glass marked War Lord.
