That's how radicalization works, a pretty well-defined tactic as I understand it:

How do you get free, prosperous, safe people to give all that up for what you offer? It sounds almost impossible. You manufacture fear and division - look at terrorism, or the uses of demonization in many places - and then they may be willing to change.

Remember that Eisenhower said, 'the only thing we have to fear is fear itself'. Eisenhower, who led the militaries of West through arguably the greatest crisis in their history, who was leading the West through the Cold War. He knew crisis, and that is what he said. That's what genuine leaders do.

Those who use spread fear and radicalization are not after security and freedom, but after power.

And, to put it more explicitly, against the people who were manipulated into fearing the "extremist" threat in the first place.
