It always “needs” a boogey man. Someone who would subjugate us? Like Nazi Germany and Imperial Japan. These types of bogey men have a tendency to recur.
It has always be like this—the Boogie men have been quite real—In order: The Indian savages, The Coruptive French, The effite elitist Brits, the British paid savages, the German Mercenaries, The trecherious Tories, the Rebelious slaves who would murder you in your beds, The Rebel slavers who would set savage white trash on your neck, The Mexicans, the outlaws, the Clever Germans, the Communists, the Russians, the Japanese, The Nazis, The Red Chinesee, the the Fanatical Japanese, the fanatical Islamic savage terrorists, —only a partial list. None of these were irrational fears—they were real enemies who would have crushed America under their heel. IS is only the newest in a list of foes. I am not saying we didn’t have a hand in making them enemies—but Enemies they are or were. Some enemies may well become friends over time—like the Brits, some we must externminate like vermin.
