i personally think the members of metallica are against war if you hear their early songs such as one you will see they are against war and how it affects people lars ulrich did in fact speak out against the war so i doubt they support what savage is doing look up some old metallica lyrics dealing with war you will see they are pretty much opposed to it as for rammstein the vocalist has stated they do not have political beliefs though they seem to lean left look at the lyrics to the song amerika and you will see they are kinda poking fun at america and american culture i think this should be looked into
