Apparently the Asian Hornet has won the battle against extermination here and the government and exterminators will just accept that the invasive species will thrive here. Money is also a big issue in this. It may or may not decimate native bee populations, but based on news articles nobody really seems to care.
At this point, I´d say have a nature battle galore. Introduce wild scorpions as they kill hornets. Breed millions of birds to kill them. Have exterminators put on three suits and fill their nests with fireworks. Have some fun, it's not that anyone even cares anymore.
I'm at least willing to defend wasps as there are a lot more of them than just the standard yellow jacket. Lots of solitary wasps, for example, are great pest controls and some even help with pollinating. Even yellow jackets are useful as pest control.
The Asian Hornet however is invasive in Europe and is damaging other insects populations and even humans.
