I'm not sure if Canada is extraditing deserters or not. A couple of years ago, there was a kid who'd headed for Canada after deserting. Don't remember if he returned of his own accord or was returned by Canadian Authorities.
However, it would also mean I could never return to the US for any reason other than turning myself in. Once I did that, I would be convicted of a federal offense which means I'd never be able to vote, hold office, own a weapon or get a professional license.
Also, I would spend the rest of my life dealing with the fact that I was too chickensh** to honor my commitment to the US Government and my soldiers. My opinions on our reason for being wherever we end up are irrelevant. I still have a duty to my soldiers to bring as many of them as I can home alive.
