10 Harry Potter Plot-Holes That Are Actually Aren't
10. Why Did No Other Nation Stand With Britain Against Voldemort?
The Plot-Hole
The British were left to fight Voldemort entirely on their own. But with the threat he poses why did other nations not send forces to help?
But Wait...
Simple, the answer here is Dumbledore.
Dumbledore was internationally recognized as the only wizard Voldemort feared. It is logical, then, to go one step further and assume that only Dumbledore could defeat him. With Dumbledore dead resistance against Voldemort would be seen as pointless, as would be sending wizards to help fight him.
Instead many nations would see to their own defence, hoping to make one last defiant stand on their home ground. Many others would probably wait to see how the war progressed in order to decide whether to spin at least a passable excuse for their inaction or just how quickly to grovel at Voldemort’s feet. Some had likely already sent envoys suing for peace.
Rather than being a plot-hole the absence of the wider world is a perfectly understandable response to an extremely difficult situation. Cause when you're staring down the barrel, it's awful hard not to cower.
