Is the world infiltrated by fallen angels?

If you're taking on an evil regime. Let's say at it's basic this fight is against simple corrupt humans.

How do you stop them from destroying the world and going down with the ship?

How do you obtain control of every weapon system, every dirty bomb, every group, every country?

How do you stop so many bad people at once?

How do you avoid a world war?

How do you do this covertly without garnering attention to it all?

What does Biblical really mean?

Now ask these questions again with something more sinister than humans at large.

The answer is simple. Accepting it, for some, is the hard part.
