Isn't the only thing that is going to weaken mankind enough for a grimm attack, mankind? So I'd think any opportunity would be human shenanigans.

Actually, I really don't see the Grimm getting a chance. Even if they completely destroyed an entire city with the element of surprise, the various militaries along with any survivors would eventually come and take back the city.
