Going slowly nuts trying to remember the title of a book

Hey all, been a while since I posted, hope this finds everyone well.

I was talking with someone at a recent sci-fi convention and someone was talking about a new book that was coming out/was already out and I cant remember the title they told me. I remember the premise and I'm hoping someone out there can help me recall the title.

It takes place in the near future when the United States has recalled all its troops from overseas and is stockpiling massive amounts of every resource it can get its hands on.

In the book, the United States govenment has discovered that the North American continet is going to be transported/teleported to some other world and they are readying themselves for whatever is going to happen on wherever they are going.

America isn't telling the rest of the world what is going to happen, and the other countries are very pissed because it just appears that America is just grabbing everything on the market for no good reason.

It sounded like a very interesting book, but I didn't have a pen to write down the title and I'm looking to those of you out there to help me figure out this mystery.

Thanks for your time and attention.
