Well, I figure if they can kill the number one guy, they can find the number 2 through 20, and kill them all. The world would never miss them. 👍
One issue with that is the law of unintended consequences. Just look at what happened when the Germans decided it was a great idea to eliminate the leadership of their enemies, the Russian Empire, in WW1. They sent Lenin back to Russia, figuring he couldn’t be as bad for Germany as the Czar was.
How’d that work out for Germany?
