I also forgot to mention that by asking solders to fight against Voldemort you’re literally exposing the Wizarding world. How many people would want wizards and witches to use magic to cure diseases repair bones etc. Point being, even if you select elite team of soldiers to “hunt” Voldemort someone is bound to talk about this withafriend orafamily. Pretty soon the whole world will find out, and they want to separate those who knows how to use magic from those who don’t. Or worst anti-magic campaign will arise anda21th century witch hunt will began. Not everyone will accept new things. Some will be jealous magic users other will fear them since they don’t know what they are capable of.
