5% of the population is 1.5 million people. That's a 'standing army' of people who would rather see the world burn then move ideologically to the right. If even 1% of that decides violence is the answer, that's 15,000 potential terrorists, and it only takes ONE to potentially hurt thousands of people.
This is almost a cold civil war, with how things are polarized now. I'm trusting the plan, but that dosen't mean not to keep an eye out.
