[HP] Where was the rest of the Wizarding community in the fight against Voldemort?

During the lead up to the final battle with Voldemort, Hogwarts didn't appear to do enough outreach, calling on other Wizarding schools or other organizations in the community, to draw attention to the obstacle that was essentially evil incarnate. 

Obviously the Ministry was a mess, and there was a certain need for being discreet in general, double agents and the like, but it seems that someone would have contacts worth calling on. 

So what's going on here?

Both Voldemort's first and second reigns of terror were largely limited to Magical Britain. It's entirely possible that other Magical nations simply considered it not their problem. An exceptional case, to be sure, especially with that Boy-Who-Lived business, but to other countries, Voldemort and his exploits may well simply be considered a curious legend or a fascinating excerpt to be included in a history book, rather than anything they personally have to deal with.

It's also possible they had their own issues to deal with and they didn't really have the resources to spare useful assets. We never really heard all that much about any of the other schools, or the countries who housed them, beyond that they existed at all, but surely Magical Britain is not the *only* place where weird shit happens, politically or otherwise.

Within Magical Britain itself, a lot of people were simply scared out of their wits and did not wish to risk drawing Voldemort's wrath.
