I'm not aware of Walt Disney being pro-Nazi Lark; I know many Disney cartoons were banned in Nazi Germany due to one cartoon showing Mickey Mouse fighting villanous cats wearing WW1 spiked helmets. Although Luftwaffe ace Adolf Galland I guess managed to get around that, since he had Mickey spray-painted on his plane throughout the war.
Disney even made this anti-Nazi cartoon:

And then this one, on a more humourous note:
