The price would go up! The US already buys the lions share... what would change? There IS a shortage of oil looming, but most folks are blithley ignoring it.

The logistical issues of invading Canada and seizing the territory are HUGE. D-Day would look like a high school project. If there were an international shortage of oil, Canada would be running low, too, not only making it a less savory target, but it would make the large expeditures of petroleum required for a military action of that scale pointless for the potential return.

I'm not saying it's not possible some (other) wacky crackpot would get in office and think it was fun to lob a few missiles at Canada. Hey, Canada has missiles -- some crackpot there could launch one at us, too. But invasion? Successful military occupation of the vast area of Canadian petroleum reserves? Do you know how big an army that would take? It's not like we can grab the stuff and bring it home with us. Uh uh.

To most Americans, I think, the idea of attacking Canada is like attacking... Kansas. Nobody is to too sure what up there, but it's big and it can't really be that exciting or they'd know about it already :)

I'm not a sociologist, I just play one on TV.
