Chapter two:
Know Your Enemy
I'm sure that my interpretation of this song is quite different from anyone else's. Imagine that this takes place in 2001. The start of the 21st century, Christian is six years old, He is a child, and his parents (or parent, as he could be from a broken home) is telling him not to talk to strangers, do drugs, etc. These are essential things that need to be told, as the 21st century is a dangerous place. We can assume that Christian was born into a bad neighborhood, hence the drug abuse. Anyways, this could be his mother (we'll assume his father left, that's usually what happens" telling him about the enemy, or strangers and drugs. Violence is an enemy. "From here to eternity" She wants Christian to stay safe throughout his entire life. the problem is, she most likely knows that it's inevitable that he'll end up fucked up and stuff. She's warning him about the dangers outside of his 's asking "Do you know the enemy?" or in other words, she's asking him what he knows about the outside world, and he's "gotta know the enemy" or else he'll probably end up like the rest of the people in the 21st century. I read somewhere that Christian is a symbol of rage and destruction, most likely due to the drug abuse later on. This song is a warning to Christian, that everyone out there is an enemy, and they have urges to hurt other people for amusement.
