I think the cities would die, and because those inside would devour themselves, consuming everything “Left”. If those of us outside the big cities united to build barriers to keep them inside, we could dispose of the majority of Democrats before the dust settles. Would not take as much ammo as one might think if they were kept inside their cities! And if we had a major war, our enemies would not bomb corn fields, they would hit the cities, another plus!
Well, the Islamic maniacs are so insanely in love with death and murder, they would set of the Yellowstone volcano if they could, and put an end to not only America but civilization around the globe with the changes to the climate. Demonic bloodlust has no rational aspect.
