Am I missing where this is quoted from, or is it like many other quotes where it could be attributed to the person, but nobody really knows?

Edit: if I'm reading right, it seems to be a quote from Dinesh D'Souza's book "What's so great about America" quoted by Henry Kissinger in his book "The White House Years"

Aside from the aforementioned countries, I'd say Israel is quite a strong ally of the United States.
