No Remorse Lyrics

Lyric discussion by TVF4 

Cover art for No Remorse lyrics by Metallica

sounds like they could be talking about Nazis:

"Only the strong survive. No one to save the weaker race" - anti-semitic/racist

"swords are like lighting" - metaphor for blitzkrieg maybe?

"Blood feeds the war machine as it eats its way across the land" - Germany's swift take over of Europe. Germany's army is the only army that I know that was referred to as a "warmachine"

Just my thoughts
