Have you got two heads?Don't know how anybody can be that dumb with only one!The point is that we trade with the USA from historical choice,not necessity.If they don't want to trade with us,who cares,apart from a lot of American jobless.They have a $6 trillion trade surplus with us-if they don't want it any more,so what?
Again, it's not clear what you are babbling on about. Are there any individual countries that we trade with out of necessity? As far as Obama is concerned, he didn't imply that if we leave they are going to stop trading with us just that we'll be starting from scratch with regard to actually reaching a trade agreement.. We can probably get anything we import from the US from other places anyway. Whether we choose to or not is down to the consumer. If US products don't sell then retailers will get them from somewhere else.
Finally, got a link to that $6 trillion trade surplus?
