Why did Nils Debruuk insist on reading the manifesto?

In Mission: Impossible - Fallout, when Team Hunt was trying to get the mobile password from Dr. Debruuk, he wanted the manifesto to be read and broadcasted on air or he won't give those passkeys.

After they read the manifesto, he typed those passwords saying:

Well, it's not going to help you now.....What's done is done.

Why is reading the manifesto on air so important to him?

If he gave those passwords without the manifesto being read on TV, what did he fear wouldn't happen? Was he trying to send any signal to anybody? If any, what was that and to who? What is the relation of "what's done is done" with reading that manifesto?

Best Answer

Because he wants people to understand

....and, in his mind, bring about world peace

He says..

"There has never been peace without first a great suffering. The greater the suffering, the greater the peace.

See, this will unite them. When they read this manifesto they'll understand."

Now, he can post it on the internet but that doesn't guarantee that a lot of people will read/hear it.

On the other hand if it's read on TV, millions of people will read it and, he hopes, be converted to his way of thinking.
