You may be shocked to know that there have been many historians who view the Atlantic Alliance as nothing more than a prop to the Anglo-American empire.
When you follow the money of the WW2 era, and you see how much of Hitler's backing came from both sides of the political spectrum in the US, you realize the depths of depravity of the elite all over this planet. You also realize how possible it might be that those people supporting him from here continued to support those like him in ideology after the war.
Maybe not because their ideologies were exactly the same, but because they shared the same lack of concern for human lives not their own, and that lack of concern is very profitable.
We weren't supposed to get into the war. It was a campaign promise of a corrupted politician who went back on his word by coercing/forcing Japan into attacking Pearl Harbor. Why? Why would he want to go back on that promise?
His campaign contributors demanded it.
Why?
Pretty simple. They backed Hitler, and Hitler had been winning. That meant more profits for them not just in terms of the weapons and other sales, but also in the stock and currency markets. Then Hitler decided to invade Russia, and everyone was like, "WTF?! NO!" They knew he was going to lose, and along with that they would lose much of their investment IN HIM.
The US had to enter the war to make sure that investment and its projected return didn't fall into Russian hands. As it turned out, a few of his backers lost money anyway. Among them was Prescott Bush, who had his assets and those of his financial institution frozen as part of an investigation by Joseph Kennedy into those funding Hitler. That family lost a lot of money and influence in that deal.
This country didn't get into WW2 because of the atrocities of Germany. They didn't do it to rescue Europe. The govt entered the war because of people invested in the outcome, and caring, patriotic Americans were shown an evil enemy they had no problem fighting. Most had no idea what was happening to the Jews, and to the political and religious enemies of the national socialist party. They just knew that Hitler, whom elites here helped to fund, needed to be stopped. And stop him they all did.
The fight that brought about the National Socialists gaining power was similar to what we saw in Russia and are seeing here now. Weakening and then federalizing the family. Pitting the poor against the middle class. Using propaganda and abuse of the purse and the citizens to foment fear and hatred, and clearly violence, as well as faking events and blaming them on political opponents.
My eyes were opened to all of this by a friend who had studied it, and seen it starting here in the 90s (but I think it might have have started in govt in the 50s or 60s). Some will just take the word of then current and even modern rewrites of last century's history (like those that have tried to rename the Bolshevik Revolution the October Revolution, not unlike them calling the incited bloodshed in Libya and such the "Arab Spring"...) I like to read all of the factual events and reason through them instead, since I've seen the omission or interpretation of those events change dramatically every decade or so.
