[Cronos]

Germans, yes, since the Kaiser reached out to the Moslems

Spain, no

Finland, no -- they saw the Nazis as the lesser, farther evil compared to the closer evil of the Soviets -- and they were right, look at what happened to Estonia

Hungary - no
Romania - no
Italy - no

[Axenolith]

Spain was shipping material like tungsten for AP rounds to the Germans to close to the end, Italy was PART of the Axis until they fell. Hungary and Romania were both allies up til near the end, both fielding units that performed miserably on the eastern front and also with respect to the latter being a major source of Germany’s petroleum and distillate needs.

The Finns were supplied their best weaponry by Germany, they didn’t on the face of it meld operational strategies, but both shared an enemy on the field.
