::::::::::The meaning of "collaboration" in the context of war is clear, you do not need to use the word "treason", since the core definition of "collaboration" is to cooperate traitorously with the enemy. Hjalmar Mäe was a traitor, Uluots was not. As I recall Finland was neutral in 1939, a co-belligerent with Germany until 1944, then after the Moscow Armistice was an enemy of Germany. Estonia was neutral in 1940, part of the anti-Nazi resistance politically from 1941 until 1944, then de facto a co-belligerent in 1944.
