Hitler wasn't arguably a Fascist, he was a National Socialist, and he was retaliating over Germany's loss of World war 1 and the treaty of Versailles.
Mussolini did more than Chamberlain to try to prevent world war 2. Fascism was not the reason for Hitler retaliating over World War 1 or Hitler's racism.
Okay, "Matt," this trolling sure is fun, but before you go down the "Hitler was a socialist!" route, consider that there are people who have studied the rise of fascism in Germany and understand the topic far better than you.
It is true that nationalism and socialism were (as Friedrich Meinecke wrote in "The German Catastrophe") the "two great waves of the age," but Hitler was not even remotely a socialist. Anyone who has cracked open a book on German history of the era can tell you that the name "National Socialist" was disingenuous, and that one of the first of many groups the Nazis began rounding up were the socialists.
And you've got that last bit spectacularly wrong.
I said Hitler was a National Socialist.
The Nazi party was such a deformed hybrid of Fascism, it simply contained toxic stuff that isn't fascist.
Mussolini put troops on the border with Austria, stalling Hitler's annexation of Austria, Mussolini told Hitler to avoid invading Poland because it was a Catholic country, Mussolini stalled Hitler's invasion of Czechoslovakia. He didn't want that war.
With the fall of France Hitler was threatening to I invade Italy for being unfaithful to the pact of steel. German propaganda was also promising to create a antibolshivek anti communist block of Europe that defends Religion against the attacks of militant secularists and atheists.
Mussolini didn't like Hitler anymore than Patton liked his ally Joseph Stalin.
Patton and Stalin were allies but they hated each other. Likewise, Hitler and Benito didn't have much in common.
