I believe I read somewhere that when the framers wrote the US constitution they expected it would have to be rewritten every generation or so. I wouldn't exactly call the US gov a long term organization at this point, but if that's true (I admit I'm struggling to find a source right now, so correct me if I'm wrong) then the current form of the US government does seem to have survived beyond it's original intent.
