Why should sovereignty mean that you can disregard the rights of foreigners any more than owning a home should result in a right to take a guest&#x27;s wallet at gunpoint? Whether or not either of these situations is morally desirable, I don&#x27;t see how they would be sustainable, as in, why would everybody else put up with you?<p>To take your example, if my country nationalizes an oil field found and owned by your country&#x27;s citizens (assuming that my country originally tricked them into searching for oil by promising it&#x27;d be theirs to some extent or other when they find it - otherwise why would they search for it in the first place?), why would your country stop at &quot;tarnishing my country&#x27;s reputation&quot; when it could apply force, ranging from economic sanctions to an actual war?
