Uh, no.
I would hope that an attempt to do so would involve the rest of the world to rally to our defence. At which point I would join the resistance to defend the country. I DO NOT WANT to live in the U.S. thank you very much.
The U.S. would be a fundamentally different country if Canada were a part of it, though. We'd probably be looking at 50 new Democratic representatives and 18 new Democratic senators overnigh, and the new Canadian states would keep running like they've been running for years.
