The Mrs. has quite a post on what the terrorist playbook is, the saddest thing is that we've encountered this playbook before.
The anarchists used the same plays to try to spark the revolution that ended up starting WWI and ended with the Bomb at WWII which begat the Cold War and the War on Terror. And all they really want is a major incident they can spin so they can gain personal power over more people. All we need to do is deny them that, and that is what we are doing, though most people are of the opinion things are going badly.
Sadly, history and most subjects really are being skipped to put more time into passing the test so the teachers will continue to get funded. This is no great surprise either, people will spend lots of time doing that which will maximize their return on investment. That's just basic economics but, economics is being skipped too.
