Did the German invasion of Yugoslavia doom Germany to inevitable world war defeat

[poiuytrewq0987]

The Kingdom back then was pretty strong militarily in numbers but its equipment was antiquated as most of them were from the WW1 era. The Kingdom had about one million soldiers for a country of 15 million. And the Balkans after the fall of Yugoslavia to German invasion only saw increased instability and insurgents constituting of partisans and royalists. Had Hitler kept his cool after the overthrow of the prince then Germany would've had gained a powerful ally in the Balkans, one far stronger and useful than Bulgaria. Germany only needed to help update the Yugoslavian army equipment with the most modern equipment available to the period. Yugoslavia also could've mobilized up to an extra million or two soldiers (in addition to its 1 million man army) to fight on the Eastern front and the Allied invasion of Africa and Italy. I believe that with Hitler's invasion of the Kingdom, he only doomed his Germany to inevitable defeat for he sealed the fate of the Balkans to uncontrollable partisan activity which used up manpower that could've been used to fight Russia and elsewhere.

Nope, the RAF doomed Germany to inevitable defeat by preventing Hitler from invading Britain, thereby allowing it to later become the place from where the Allied invasion of Europe was launched - a crucial diversionary tactic that allowed the Russians to defeat Hitler.

The Reds did it.
