I looked it up. They were both consultants with the Boston Consulting Group early in their careers. They are approximately the same age. Netanyahu graduated from MIT, and Romney from Harvard, so I was wrong about school together. But they went through the BCG “boot camp” together as young professionals and their lives have intersected regularly — proffering advice to each other as their careers developed. Because of the BCG boot camp experience they almost speak in “shorthand” to each other.
I knew they were friends from way back. Cool. Seems they are both very accomplished men.
