Cracked.com applies Fridge Logic to the Ministry of Magic

[Labster]

So, yeah, in reality, every single intelligence agency in the world
would be toiling in secret with one goal in mind: figure out how magic
works, how it can be countered, and how every wizard in the world can
quickly be assassinated before they figure out what's happening. There's
your eighth Harry Potter book, JK!

This is what happens when you apply realpolitik to fantasy worlds:  A world where the crazy shit done by the CIA, KGB, et al are actually justified.
They did fail to consider one thing: that if Osama bin Lestrange did sneak attack the muggles, The Doctor would just swoop in and save England.  Imperius curse doesn't work on Time Lord physiology, duh.  This is also what happens when you apply realpolitik to fantasy worlds: literally anything could affect your calculus due to the number of unknowns.  There really is a lot of room for fanfic to make sense of the canon.  But rather than taking the xkcd What If? approach, you'd be better served by asking what would make the wizarding/muggle world relationship homeostatic.
