The nation which is threatening the other with aggression, and nuclear weapons if it so chooses?

Or the nation which isn't threatening aggression?

The nation which has publically announced that it is trying to assassinate the other's leader, or the nation which is hunkered down not announcing aggressive or murderous intent?

The nation which is stacking up arms and forming alliances to invade the other nation, committing "preemptive aggression", violating the standards of human decency as well as the UN charter it signed, or the other one?

Who is more guilty, morally, the rapist or the rapee?

You're right. No equivalence.
