Israeli Prime Minister Benjamin Netanyahu has two obsessions. The first is a case of chronic miserliness, which he shares with his wife. They have become addicted to living off of others, sometimes even against the law. This obsession got him into trouble in the past, culminating in a criminal investigation in 2000. On Feb. 13, it got him into trouble again, when the police recommended that he be indicted for bribery in what is called Case 1000 (Netanyahu allegedly receiving benefits from businesspeople).

Netanyahu’s second obsession is everything to do with the media. Although the free newspaper with greatest circulation in Israel has been subject to his every whim for the past decade, and although he has the most popular Facebook page in Israel, Netanyahu continues to meddle in the Israeli media market, trying nonstop to gain control of even more chunks of it. This keeps him busy 24/7. As we have now learned, it has also gotten him into hot water with the police.

Case 2000 involves explosive recordings of conversations between Netanyahu and Yedioth Ahronoth publisher Arnon Mozes. Last week, these recordings also resulted in a police recommendation that Netanyahu be indicted for bribery.

But this is just the beginning. For the past few weeks, the Israeli police have been conducting an intense covert investigation, entirely under the radar. It is called Case 4000, and it dwarves cases 1000 and 2000. In fact, it is so potentially dangerous that it puts Netanyahu in serious risk of facing criminal proceedings.
