“I doubt that they realize that they are building the kingdom of antichrist.”
1. They are building a Brave New World.
2. They are not educated enough to understand that that is a bad thing.
I do not know the truth, of course, but I suspect they are cleverly deceived. As you say, they think that they are building a Brave New World. The kingdom of antichrist will be the only way to establish a one world government; Babel must be undone.
I have posted my thoughts here and here... if you have time and are interested.
