Why must we continue to look for monsters to slay? There is only one country in the world right now with the industrial might of 1930s Germany and anything close to the iron will to conquer the world, and Hitler ain't here.
While the evil Versailles treaty after WWI created Hitler, there was little Europe could do to stop him. In the end it took what was left of the British Empire, the Soviet Union, and a fully committed United States to bring him down. Nothing less.
Iran can't stop the incursions by our Special Forces. Neither could Iraq. Venezuela is a slave to the high oil price. North Korea can't keep the lights on. The reality is that there is no new Hitler, and to dream him up is only invective.
