This is ahistoric drivel.
China and Russia are simple examples of the fallout of "cutting king's heads".
So awesome in China that they went straight back to a lifetime emperor now.
The French Revolution and its fallout (communism, fascism) killed more humans than any other historic movement, triggering 2 world wars, including numerous genocides.
Blaming an event that happened in 1789 for the first and second world wars seems incredibly far fetched. Maybe we should blame the aggressors who started the wars.
