Professor Rubin was a much-respected and prolific scholar and, of course, a doughty champion of Israel's cause. He was an expert on terrorism and Middle East issues, and his outstanding analytical online articles will be much missed.
He leaves behind a number of wonderful, highly informative and greatly recommended publications, some of them available for free (see here)
As I mentioned some months ago, among his output is this book, just released. I have ordered it, and keenly look forward to reading it. It promises to be a must-read.
His untimely passing is a tragic loss for Klal Yisrael.
May his memory be a blessing.
