Two can play that game. Any half-way intelligent science teacher or engineer could easily put together something that would leave New York City, Boston, Atlanta or Los Angeles uninhabitable for 100 years. Look at the IEDs coming out of Iraq and Yemen. Biowarfare would kill people in red and blue states.
So it would. But that’s supposing the democrats worry about killing their own. All experience say they don’t. Same with the muslims: no one kills as many muslims as other muslims. The important thing is that the killing machine ticks over.
The communist/islamist kadres tend to be small, they just need masses to whip up. And the masses mostly do what they’re told.
