Doug Casey: Let's define this term exactly. The Oxford Dictionary defines a false flag as "A political or military act orchestrated in such a way that it appears to have been carried out by a party that is not in fact responsible."
The concept of false flags has gotten a bad reputation in media and government circles and perhaps with the population in general, because they've come to be associated with conspiracy theories. And "conspiracy theory," whether valid or not, is used as a pejorative. While there are definitely some people out there with tin foil hats, the establishment likes to label any beliefs that don't follow the party line as conspiracy theory.
In fact, false flags make all the sense in the world for someone who wants to start a war or who needs a cover for some other criminal enterprise. You never want to be seen as the aggressor or the bad guy. You always want to be able to blame what happens on the other guy. If you're going to start a war, you want to look like the innocent aggrieved party in order to get the population on your side.
