I totally disagree with you. The Nazis and ISIS’ goals are the same, only the tactics are different. You are now seeing SOME OF THEM ‘flee’ from Libya into ITALY. And how many local terrorist groups throughout the world have announced their alliance with ISIS, such as Boko Haram? A Nazi wore a uniform, ISIS doesn’t. Same goal, different methodology. Just as much a threat, IMO.
While I agree with you on the goals and methods of ISIS vs Nazi's, they are worlds apart in relative capability.
Nazi had a reasonable probability of taking over the entire world.
ISIS is a large street gang with no manufacturing, R&D etc. None would survive a day against a modern military assault.
