This is an article from 1996 in something called the Washington Report for Middle East Affairs. Here are some facts about Benjamin Netanyahu as reported by this article.

1. He went to high school in suburban Philadelphia. (I looked up elsewhere, and it was Cheltenham high school. This is a public school district in a not particularly posh area.) Then MIT.
2. He was a dual U.S.-Israeli citizen, at least at that point of graduating MIT.
3. He has gone by at least four names. One of the three alternates is just a shortened version, but the other two are John Jay Sullivan and John Jay Sullivan Jr.
4. His social security file is marked “classified”. According to this article, that suggests he may have been on the payroll of the CIA or FBI.
5. To run for office, he had to give up his U.S. citizenship, which he did legally in Israel. But in the U.S., at least according to this article and in 1996, he was still legally considered a U.S. citizen. (This situation is not unusual though, as I know plenty of people in ambiguous dual citizen categories in their home countries for one reason of convenience or another. An innocent one is because someone lives in the U.S. but wants to visit family in their home country for an extended period without applying for a tourist visa.)

The article veers into some interesting territory from there, but I found these apparently fact-based nuggets interesting.
