Very briefly, I would say it's about war.
It does mention 'war machine', but also the concept of white and black- i.e. right and wrong (we are right, our enemy is wrong) and that in war, many of the rights/ wrongs we know are turned to grey- i.e. killing others is clearly wrong, but in war soldiers and not only encouraged to kill, killing is a necessity!
Wars are often fought for territory (Vietnam war, WW2 etc) as well.
Ideals- political differences and power are also key instigators of war- 'antiquated lost ideals from the oppressor'- the leader of a nation or political party who has lost touch with their people and have turned into a tyrant.
