Wounds don't heal cleanly unless you clean them, that's the point.

Thta's a rich analogy too - real wounds which aren't healed flare up later, and the stuff left inside to fester can even kill people.

What's really needed is a proper truth and reconciliation commission or something along those lines. If that had been done back in the 20s maybe the last generation wouldn't have had to live through an interminable war. It's lies and whitewash and cover-ups and selective memory that breed hatred as much as anything.
