I think I figured out "Sabaton"

[Mortimer]

They are neither pro nor anti nazi, they are probably into white brotherhood. They glorify both, the axis and the allies. Pro axis: Ghost Division, Red Baron. Pro Allies: Primo Victoria

Now i found this song "american troops and german army joining together" so i think they probably like both the germans and the americans/british

i know they are swedish metal band. i dont know about their politics.
