It would be difficult not to notice the occurrence of the Second Wizarding War since it broke out by the fall of the Ministry of Magic (MoM) in the UK. Additionally, Voldemort's rise to power was compared to that of Grindelwald's that affected the wizarding community across the globe. So I'd assume that the American Magical Community (AMC) was aware of the magnitude of the Second Wizarding War and its supposed consequences if Voldemort had won.
Questions here and here talks about why the other [European] wizards (from Durmstrang and Beauxbatons), didn't come to aid during the Wizarding War.
However, I could not find anything that mentions the role AMC played during the war against Voldemort.
So, was the AMC involved during this war? If not, is there a reason why they decided to stay away from this conflict?
