Let's look at what's been going on.
- Some 17 terrorists get picked up in Canada with enough bomb-making equipment to take out a large swath of Toronto or functions of the Canadian government.
- A cell in London is picked up -- but after a dirty bomb is deployed, probably to be detonated at a sports bar during the drunken World Cup festivities.
- Two weeks ago, a pair of Saudis are picked up after climbing on board a school bus in Tampa, perhaps a forerunner to a Beslan-type massacre in Florida.
Something big is brewing, and we're seeing the first signs of it.
