I don't know if they realize how it will all play out.
But from the Bible, at some unknown point in the future, there will be a leader that all the world worships and he will bring about the one world government.

Look how well they brought about 2020.
In this day and age why isn't there tech that allows air traffic to see each other and communicate with each other?
