Which Of The Former Leaders Had The Most Evil Technique To Loot His State?

Hey y'all! Let's try something new . Not to praise these thieving fools or anything but I'D like for y'all to tell me out of all the former leaders, who had the most sophisticated and well devised scams to loot his state? Also tell me base on the severity of the looting what should his punishment be? It could be more than one looter. I think obj for me. His power sector scam gets first prize! Following him would be ibb.
