What does this mean?

I’m reading A Seperate Peace by John Knowles for a summer assignment and I’ve done almost all the questions but it says to interpret the last line of the novel, so can you help me?

All of them, all except Phineas, constructed at infinite cost to themselves these Maginot Lines against this enemy they thought they saw across the frontier, this enemy who never attacked that way – if he ever attacked at all; if he was indeed the enemy.

it means that everyone except phineas got caught up in mass paranoia and spent all their resources drawing a line in the sand to protect themselves from unseen outside enemies, when in reality that enemy may not have even existed.

I’m unsure if I’m helping you or not but here’s a link on A Seperate Peace in the Wikipedia at the source list below. For me to interpret something, I would need to read through the whole thing. I apologize if my reply is absolute nonsense to you.

I think this means that he is seeing from there prospective because when ur in a war both sides think there not the enemy.
