The BBC explains black flag (aka false flag) operations.
Other False Flag ops: The Gulf of Tonkin, Reichstag Fire, Operation Northwoods, 9-11, and to some degree the Lusitania, Gulf I, and Pearl Harbor. We baited the enemy in the latter 3 cases.
Do I believe all of these? Not sure. But the video certainly makes you think about the lies the government makes to justify world policy.
