Kissinger was referring to a famous line of Palmerston, who of course was speaking of the UK. The statement doesn't apply to one country.

(Edit: that might have been clearer with one more word: The statement doesn't apply to just one country.)

Of course it does, but it's still not understood by all.

I don't think I understand your comment, but in case my meaning wasn't clear: bringing up that quote in this context and acting like it applies to one nation more than others is flamebait. Nothing good can come of that.
