I shouldn't even be here, except that you are pissing me off, Dio.
Mihailovic helped rescue the American Airmen in late 1944, and the Germans wanted the Americans as badly as they wanted Mihailovic, but Mihailovic wouldn't turn them over. The Germans burned a Serbian village with the inhabitants in it in retaliation for not handing over the Americans. Anyone interested in the subject should read "The Forgotten 500" by Gregory Freeman.
Seems to me, Dio, that you are only to happy to regurgitate Tito communist propaganda, like this "Mihailovic was a collaborator" nonsense when it suits your aims, but label anything you don't like as "communist propaganda" or "Serbian propaganda" when you are losing an argument. Grow the hell up!
As stated before, Mihailovic played a double game with the Allies and Axis, collaborating with the Axis to stop the Partisans, and hoping for an Allied landing in Dalmatia at which point he'd switch.
Facts are facts, Boka. And the fact that these facts come from Chetnik sources in the West post-war make them all the more solid.
