According to scripture Yahweh has control over the evil, and the good. You may think the illuminati are the ones controlling everything but that is not the case. Nothing happens to Gods creation without his permission, and God does have satan on a leash. How much leash does God give satan? More sin means more leash. The amount of destruction satan is permitted to do is directly related to how much sin is in the world. Explains a lot eh? Satan is being used to carry out judgment by being given more leash to run around on. Some things may be a direct result of Gods hand, and others may be satan messing around on the leash that he has. Either way, God has control over all plagues, wars, and natural disasters regardless of how they come about.
