Concern for the sovereignty of nations runs like a drumbeat through almost every debate on foreign policy. Are corporations exerting too much influence on sovereign governments? Is a larger power pulling the strings of a smaller one; are international bankers putting too much outside pressure on some nation’s treasury? Is a humanitarian crisis severe enough to warrant breaching a border?
The idea of the world as a perfect patchwork of self-ruled nations is so essential to our understanding of how the world works that we’re rarely aware of it. When we worry about wars, or trade disputes, or multinational companies throwing their weight around, we’re worried in part because we see these as disruptions of an otherwise neat and stable system of sovereign states.
