I think even with TTL Rommel surviving and receiving a free card, in general the Wehrmacht won't have a good reputation in Germany post war. Besides, what the Heer did in TTL '44 could be a possible seed for future neonazi movements in Germany (the generals betrayed Hitler, triggered the civil war, the Reich could have won without their treason).
I think neonazi movements out of Germany won't emerge, if else because certain impulses would be kept in back and absorbed between fascism as established third way ideology. In short why a wannabe dictator would take the steps of Hitler when Mussolini TTL would be a more successful model to follow? Naturally there would be guys who would follow this former path and I see a case in particular (which would be a petty nuisance for TTL Italy as for Israel as well).
About the matter of decolonialism: naturally there would be more resistance from France and Italy. About Britain I am not so sure despite if Churchill wins in 1945, could adopt a more resilient stance in Africa - Asian colonies would go anyway but the fate of the European outposts in China could be slightly different, in particular one place: Tientsin.
But before delving more about this particular issue, would be important to know how the Pacific war was going and how Japan reacted to the chain of events triggered between the end of 1943 and start of 1944 by the Germans...
