Hitler is the devil of our secular liberal religion. The name or the specifics is no longer important. He is important as a sort of religious symbol whose name can be invoked to summon the cattle to do things. Every enemy in every war from now to the end of time is going to be "the new Hitler". They are always going to be accused of planning to both conquer the entire world and open new death camps were they will kill exactly six million people again.
New Hitler always comes to power by hypnotizing all the good people of his country into doing evil and then destroying "liberal democracy".
Immediate war is the ONLY choice in dealing with New Hitler because if everyone had just attacked Germany as soon as Hitler emerged, he would have been defeated.
You can't make deals with New Hitler because that is "appeasement" and it leads to Paris falling or something.
You can't negotiate a deal with new Hitler because that is a "Munich".
You must always prepare for war in times of peace because there is no knowing when New Hitler will reappear.
New Hitler always has conspiratorial followers in every other country and under every bed. That is why censorship is totally necessary to defeat the enemy within.
Morality in a war with new Hitler is nonsense. Unless he is stopped, new Hitler is going to open death camps and kill everyone. If we had to kill <insert here> number of civilians or use normally terrible weapons like <insert here>, its totally necessary because PUNCH NAZIs. Expressing hate toward entire ethnic groups is normally not cool. But if New Hitler appears, its what everyone should be be proud to do.
After the victory in the war, the next step is always "denazification". Because "denazification" worked in 1945. You send in troops, you open education programs and magically New England town hall democracy appears. And what worked in 1945 in Germany is certain to work in 2004 in a place like Iraq. Because people are all cattle.
The conditioning on this stuff is so fundamental to the education systems across the west that it acts as a deep implicit psychological trigger in at least 75% of the population. You tag a person as "new Hitler" and its all on autopilot from there.
