Not exactly, it's pretty even actually, because it's really all the same people and all the same territory. Partizans did the exact same **** the Cetniks did. It's not like anyone was special.
****, it's for this war we're the reason the term "ethnic cleansing" is in the English lexicon. Make no mistake from what the government is telling you (and let's be frank, that IS why you think he's innocent, not because you were his buddy and with him to witness his innocence), everyone who had any rank above lieutenant in our war was guilty as sin, and should hang for the **** they've done.
Trust me. I've been there. Personally.
