The 9/11 terrorists thought of using crop dusters, but that wouldn't have worked in or near a city. OTOH, it would be VERY effective in very rural areas; or don't you plan on growing your own food?
Nukes are also WMD. And even dirty bombs will kill plenty of people who live in a no man's land of your own design.
What? You think that plague and small pox have never been found in rural settings? Are you for real ?
If EVERYONE were to leave the cities and disperse, just how much open space do you think there'd be then? The government owns a lot of our open spaces, large agribusinesses ( food farming as well as lumber ) own a lot of land, and there are great swaths of uninhabitabl land. So, just WHERE is everyone going to move to and still be so far away from everyone else, that your ridiculous scenario works?
And since like Mao Tse Tong, you want to depopulate the cities and suburban areas, just were and how is there to be specialized hospitals, T.V. and radio shows, publishing houses,museums, manufacturing of things, etc.?
You really do come across as something rather like an old hippie back to nature lout/Marxist/Luddite/white supremacist combination. And like them, your views are unfeasible, ridiculous, and not at all well thought out. And, you are a coward to boot. Hardly what one imagines a Conservative to be, In fact, from your posts, I doubt that you are one.
Well don't blame me if we haven't enough room.
I've been railing against America's run away population growth from immigration for nearly half a century.
The hospitals and some factory production--providing we reverse offshoring--could be a problem.
But probably could be gotten around.
Perhaps just the hospitals could be placed in underground bunkers.
And much manufacturing, publishing, entertainment, etc., could be done at home (desktop publishing, podcasts, home-made goods, made better than ever thanks to modern tools and computerization).
Although I personally could do without most of those things, anyway.
But don't get me wrong, we would also attack terrorists who attack us, but we should otherwise avoid making other people mad at us.
Most likely the 911 terrorists--most of them Saudis; none were Iraqi--attacked us because they saw us as propping up a dictatorship in Saudi Arabia.
And so we also become the targets of Saudi Arabia's revolutionaries.
Imagine how the Thirteen Colonies would have felt about any country who aided King George against us.
