Personally, I put the proletariat of settler colonies in a different category from (in your example) European and Japanese proletarians.
The genocide of native peoples underlies the existence of settler colonies in a way that it does not for proletarians living in bourgeois "homelands". In other words, you can remove colonialism and genocide from the histories of Europe and Japan, both places would still exist in a similar sense. Remove said crimes from American or Australian history and both would cease to exist in the same sense.
This makes the proletariat of settler colonies much more resistant to the idea of revolutionary justice because for true justice to be done, their countries must cease to exist.
