Is this a very old joke? A Greek lands on a beautiful uninhabited island and writes a poem about it. A Roman finds another beautiful island devoid of people and he builds a statue to himself there. A Celt finds yet a third island with no people and starts a fight. **I just thought of a variant:** Instead of building a statue the Roman conquers the uninhabited island. But perhaps the original joke implies that -- maybe when Rome conquered a place it erected statues to the general who did this or the emperor. In fact, I am pretty sure they did. Moreover, since conquering is a sort of belligerent action, maybe there is too much similarity between the Roman's actions and the Celt's.
