I guess I'm more of the -"friends of my enemy is an enemy of mine"- type of thinking.
Understandable. A flip side of that - something
not in our interest? - is that we'll end up with
far more enemies than is necessary. That
"you're either for us or against us!" crap does us no good, in the real world, unless we want to force people to be enemies everyone. I hope we do not.
Brazil is an up and coming power, a very significant power in this hemisphere... no reason to call them enemies, because of who they're willing to have relations with. Most countries in the world have an ambassador in Tehran; we do not.
