Now, please don't misunderstand me. When I point out that all our wars for a thousand years have been fought in other people's countries, I do not mean that any of these wars was necessarily aggressive. They may well have been, everyone of them, defensive. But plainly they were not defensive of soil, territory. Of what then were they defensive? They were defensive of the nation's interests, rights; interests which may well collide with the interests of other nations in any part of the world ... Nations do so differ as to what their respective rights are and differ sincerely. And often the question, which of the two is right, is extremely difficult, as anyone who has attempted to disentangle rival territorial claims in the Balkans or elsewhere knows only too well.
