没有永远的朋友，只有永远的利益是谁说的

英国Lord Palmerston(1784–1865)说的。原话是“?没有永恒的盟友，没有永恒的敌人。利益万岁，一以贯之。”

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.

speech, House of Commons, 1 March 1848

只是丘吉尔引用为“Neither friends nor rivals are everlasting，but only profits”再加上名声太大，后人不辨真伪以讹传讹。
