PING!
Mihailovic's one overarching goal was an independent Serbia.
He started his WWII engagements as an enemy of the Nazis and fought them.
When the partisans threw in their lot with the Soviets, he switched sides against them and worked with the Nazis in order to delay a Communist takeover of Serbia.
In the meantime, he hedged his bets by helping out American and British military and intelligence however he could.
His thinking was probably that whatever ground the Nazis held would be surrendered to the Americans and English in preference to the Soviets, so that it was in his best interests to assist the Nazis and to build a rapport with the English and Americans.
When the English and Americans effectively ceded control over the Balkans at Yalta to the Soviets, Mihailovic was left high and dry and his Nazi connections gave the new regime all they needed to eliminate a prominent opponent of their rule.
Awesome!
Just Awesome!
