Because the United States government is so grossly dysfunctional that a blatant real world re-enactment of Wag the Dog[1] has gone off without a hitch. "Without a hitch" in the "distract from the President's rape of a child" sense of the original film, of course.
You may be grossly overestimating the amount of thought than went into this:
"For instance, Israel has bombed a park in Tehran called "Police park." It has nothing to do with the police."[1]
