Two Dogs Friends

Regarding this aspect of international relations, Lord Palmerston said:
“Therefore I say that it is a narrow policy to suppose that this country or that is to be marked out as the eternal ally or the perpetual enemy of England. We have no eternal allies, and we have no perpetual enemies. Our interests are eternal and perpetual, and those interests it is our duty to follow. ”
This is often paraphrased as: "Nations have no permanent friends and no permanent enemies. Only permanent interests."
The word "friendship" can be used in political speeches as an emotive modifier. Friendship in international relationships often refers to the quality of historical, existing, or anticipated bilateral relationships.
