The nature of the German regime is very relevant to why the diplomatic landscape was what it was.
I tend to agree.
No one, no one, foresaw the depths of depravity to which National Socialism would sink. But the brutal, thuggish, well-documented attrocities commited during their rise gave anyone with a pair of eyes pause. And of course you have idiots like the King of England and his . . . woman . . . more than willing to acknowledge and accept the Nazis into the realm of nations before the British wisely forced the abdication and exiled them to the most remote backwater possible.
England, foolishly, went out of its way to appease Hitler, thinking some reasonable adjustments to the peace treaties would ensure no escalation of hostilities. However, this gave them tremendous positive cache for diplomatic spin, which they milked very successfully, when events on the battlefield made it overwhelmingly apparent Hitler would not be happy until he had Europe on a leash.
No its not. Its not relevant at all. Within the public discourse of western nations today it is controversial to question the proposition, "the Nazis were evil", I'm happy to debate that question if you can find a forum for us to debate that question. I think Paradox have made it quite clear that the don't wish to be that forum. But whether you or I or today's public in general think "the Nazis were evil" is irrelevant:
because the Nazis clearly weren't considered evil at the time, The Finns a Liberal democratic regime formed an alliance with them. The Swedes gave them military transport. Other regimes allied with them. Only two nations, Britain and France actually went to war with Nazi Germany. I'm not counting nations like El Salvadore and Saudi Arabia who made empty declarations to keep the Americans happy. Roosevelt had to promise not to go to war with Nazi Germany in order to get elected. The Communist parties of Britain and France opposed the war, prior to Barbarossa. The Communist parties in Nazi occupied countries bordered on collaboration prior to June 41. The Soviet intelligence agencies shared intelligence on opposition with their Nazis counterparts. The Trotskyists continued to oppose the war even after Hitler attacked the Soviet Union. Many Ukrianians and Baltic people welcomed the Nazis as liberators. There was an uprising in Iraq in order to support the Nazis.
You are not necessarily wrong, but there are issues.
Where you hit the nail on the head is suggesting 'Evil' is in the eye of the beholder. All you have to do is look at a country like Argentina, who declared war on Germany at the very last minute to be on the right side of history, but opened the doors wide to import every Nazi bastard the Roman Catholic Church could import through the Ratlines. And unbelievably today, it is not hard to look around and find people who adamantly believe Hitler was the greatest human being that ever lived.
The problem with this statement is there is no clear, distinct dilenation of the time frames involved and you are shading legitimate facts to prove your point. For example, your Roosevelt comment is only partially true; the Americans were not adamant against fighting Naziism, the Americans didn't want to send their sons to solve Europe's problems for them. Again. America First. Roosevelt called the American Isoltionists 'shrimps', because they had a nerve cord but no brain; and FDR's willingness to oppose Nazi Germany 'indirectly', whether it was Constitutional and Legal or not, is well documented.
Nothing is evil in the beginning, it is a process of evolution to move from inception into pure, black, evil. And, National Socialism followed that path from a 'benevolent' power seeking to force Germany back into its proper position within Europe to plunging Europe into a Hell we cannot fully discuss here.
