Nibiru had one full rotation since inception around the sun. On the second rotation, Nibiru struck Earth and (Because Nibiru is Satan, that which rivaled the Father) life was created (The dinosaurs were completely destroyed). For an undetermined number of rotations, what was left of Nibiru was banished from creating again (Impacting Earth again). Perhaps no full rotations have actually occured since then.
In any case, Nibiru is coming again. Watch as we find there is nothing we can do about it. Will they fire nukes? No, we need to keep some to keep our people safe, we can't fire any. Well, actually we can fire some and still be safe. So they will and those who didn't will attack an undefended prey.
Chaos on Earth is the will of Satan and Jesus, as they both sit beside the Father (As Aeons, all three of them are characterizations of simple time progressions). All chaos on Earth is a mix of these three things.
Like I said, watch and see how little anyone can do and why.
