You can't just target one specific nation. It's the reality of it all, there is too much interdependence and too many issues at hand. Governments are forced to weed out what is beneficial and what is not. More rather who is beneficial and who is not, who is a threat and who is not. There is no goodwill done without reason. Reality hurts, welcome to pain and suffering. As for your last question: if you stop the murderer, do you stop the crime?
