And on and on we go, round and round in circles. What is the point? Sleuth's arguments are equally as valid as yours Worldsgreatest, or anyone else's. One can find statistics and numbers to support any claim and there's always another way to spin an argument in your favour. Likewise, pick a time that suits your argument, an era and sure you've got something to back up an otherwise tenuous claim but it doesn't reflect the nature of a changing world, economies going up and down, enemies who become friends, friends who become enemies. Countries and governments just like people have a right to change their mind and allegiances.
I'm not sure what people want from any country let alone one (the US) where people believe in their inalienable right to have everything they want right now. Leaders end up doing whatever it takes to protect the interests of its people, (to get re-elected). Often their interests will be aligned with those of other countries (see the list of nations who supported the Iraq war) but like some one else said earlier, you're also bound to piss someone off.
Maybe Obama will in fact turn out to be the Messiah and will right every wrong in the world... I'd be happy to be proven wrong about him.
