Is There Any Nation That Has Never Invaded Another Country?

I don't think there is any nation, or any geographical part of the world which has never been invaded and never conquered. You go back far enough in history, every part o the world has suffered invasions and conquests by a other powers. Yeh, maybe the swiss never tried invading anybody. If you look at the nation state of switzerland, maybe, maybe that could be the case. So, yes, that's just how it is. The states system is a very new system. It goes back to thea a, the treaty of westphalia, which is quite recent, relatively speaking. And so on. Si, that's the answer, ok.
