[Harry Potter/MCU] How did the Wizarding World react to The Snap?
gpt
The problem about saying "the wizarding world" is it's the same as saying "how did 21st century Earth" - there are a lot of nations involved in that description and there isn't going to be a unified response to anything.  

However, in general terms the response can be characterised like this:

1. Panic  
Initially, wizards across the globe believed that they were under some sort of magical assault, so there was a lot of running about and use of defensive spells.  When it became clear that no further assaults were coming, a lot of attention was directed at America.  

2. Blame  
It is absolutely and without question awful that, at least initially, the wizarding world thought that the USA must somehow be responsible.  Especially since the last two Dark Lords have come from Europe.  But that's modern Wizarding politics for you.  

3. Investigation  
Calmer heads soon prevailed, because some people had actually started asking what on earth had happened.  The nice thing about magic is that it's good at providing answers.  Once it was determined that the effect came from an artefact not of Earth, the Wizarding world moved right back to...
4. Blame  
Come ON, America!  You had the Avengers!  You had SHIELD!  You had a much larger population of Wizards!  You had the Sorcerer Supreme and the Norse God of Thunder, ffs!  How did you manage to drop the ball on this one!  Obviously, because the Wizarding nations of the world are a secret population themselves no one thought to lay any blame at the feet of Wakanda, and rumours of Wakanda being a long standing tourist destination for wizards have been hotly denied.
