Nasty vicious creatures are Slamolians. Russians blew up a Slamolian pirate boat. It made good sense to do so. Very vial are they, deport them all back to Slamolia. Blow up there ports, aitports and all roads to and from Slamolia. Have robot machine guns ring that place to prevent them from infesting the rest of the world. Its about 90% uninhabited so it should be easy to keep them penned in.

Let them return to the stone age which seems to be what that actually want.
