I feel like it takes place in the past.

Also, I'd like to point out a similarity with "Time to Say Goodbye":

TtSG: "Were we born to fight and die

Sacrificed for one huge lie

Are we heroes keeping peace

Or are we weapons pointed at the enemy

So someone else can claim a victory"

The credits song: "All your faith in ancient ways

Leaves you trapped inside a maze"

Both lines imply that SOMETHING is wrong the way things are done.
