If the Christian West didn’t recover from the first war, it certainly didn’t recover from the second which was a direct result of the first. How many millions did Princip kill with those two shots?
And the irony is the Ferdinand was far from being an oppressor of the Balkan peoples. He would have given them expanded rights and representation as Emperor.
...which would have diminished the attractiveness of the extremists, who wanted even more than "rights and representation," and who therefore assassinated him.
