Yes, there is a credible threat, but not from where you might think.
If I were a terrorist and I wanted to destroy the American way of life, I wouldn’t use planes and bombs to kill folks, that’s too risky, you might get caught, or killed, or both. Real terrorists get results. And then they lay the blame where it can’t be found.
Here’s what I would do: I’d foreclose on millions of homes and kick people out of their houses and destroy their primary retirement nest egg in one fell swoop. I’d allow corporations to raid pension funds. I’d devalue the dollar so the price of everything would go up. I would outsource their jobs so they couldn’t find work. I would move manufacturing to foreign countries. I would make education unaffordable. I would make health care next to impossible to obtain and let the insurance companies ride roughshod over the populace. I would make it much harder to vote. I would facilitate in every possibly way to create as many felons as possible to fill my privately-owned prisons and ensure fewer voters in the classes that most resist me, and I would use the profits to lobby for more stringent laws demanding long mandatory sentences. I would listen to their telephone calls, monitor their emails and use that information to really stick it to them. I’d give myself a huge tax cut, sit back in the lap of luxury and watch them fight over the crumbs. Then, I would empty the American treasury into the coffers of my true masters on Wall Street and beyond—the people who pay for my political campaigns.
But you know what? Thank God we live in the United States of America, because in these United States the people who represent us would never, ever let terrorists get away with that.
