Here's what I suggest:
Reject every conclusion the creator of this video has to offer. Watch this video with pen in hand. Write down every factual claim the speaker makes and—as I said—ignore his conclusions. Put a check mark beside the claims you know are true. Put a question mark beside those about which you're uncertain; look them up later.
Then come to your own conclusions. Ask yourself one question: Given that we live in a world governed by the Law of Cause and Effect, what may we reasonably expect to happen if events continue on their present trajectory?

Will we see a nuclear World War III in the next few years? Consider the wise man's reply.
