Seems like the "false flag" term has been getting a little overused lately. Expanded provocationary terms should be developed to more accurately portray each event. Since the two groups you speak of fly the same "flag" using that term wouldn't quite be right, it needs to be something reflecting the CON-fidence game that is US politics. Something that explains the two wings of the same bird, flapping at each other in order to make the bird fly ...up the flag pole. CON, Each wing is with and against the other wing.
Sorry if this is even more confusing, something to ponder.
