Oh yeah. Drop the value of the USD by 50%, I dare you. So tell me, what doesn't the USA import?
For the most part, our politicians. Notable exceptions being gov of California.
Not sure that we import many weapons, since we make so much at home.
We have lots of corn and pigs.
So what's the point?
My point is that the sudden doubling of the price of oil and every other import would have a profound effect on the USA. It might be desirable anyway, despite the cost, but it is not something that can be done on a whim without any consequences, as the parent to my comment seemed to suggest.
