I suppose Rafic Hariri isn't "random" as he was after all Lebanon's democratically elect Prime Minister when Hezbollah assassinated him, but how about the 21 people who also died in that bombing?
I personally know a man who lost his wife (mother of their 3 kids) when Hezbollah bombed the Jewish Community Center in Buenos Aires. 85 civilians were killed, but then again mostly Jewish so not exactly "random" either.
It always amazes me how many Western activists approach the world like a Hollywood movie. If Saudis are bad, and Trump is bad, then obviously their Shia rivals must be good!
