There's no unscrewing it quickly. If we could execute a decades-long plan (we can barely execute a quarter-long plan so that seems unlikely) the information needed exists, it's "just" a matter of having people learning how to implement it again & building the needed equipment. And that's largely an economic problem, and thus politically infeasible. But the skills were invented by people who didn't have training from others in how to do those skills, it's not inherently impossible to re-develop them, especially since there's documentation on a lot of the skills. It's just difficult, slow, and expensive.

We are screwed, we did it to ourselves, and we're not willing to pay the cost to unscrew it.
