Everyone is missing Modi or the Saudis as an option here. Hitting Mohammed bin Salman with it and just waiting is a winning option.
Honestly any billionaire is an option too as they have such incredible wealth that literally any of them could fund multiple revolutions and the growth of a dozen communist parties worldwide.
I’m assuming this laser turns people into communists, obviously.
Salaman or MBS might be the best choice here. He has a ton of power, the only way to oust them is through a major regime change because of monarchy. Most importantly, Salman has 18 bil and MBS will inherit that plus a bil or two of his own. Even if disposed or merked they could have someone distribute the money and fund various revolutionary groups through China.
