It’s (The Lavan case) not the only case.
The attack on the USS Liberty by Israeli air and naval forces towards the end of the 1967 war is hardly known, and among those who know, most probably accept the official story (regrettable accident) — though plenty of prominent figures in the Pentagon and government don’t. Same with the Iraqi attack on the USS Stark in 1987, also killing several dozen sailors. In 1981, according to the Israeli press, the Israeli air force sent US jets over the Saudi oil fields in a not-so-veiled warning to the US not to consider an Arab peace proposal, much like the international consensus that the US has blocked (and Israel opposes) for 30 years. Who knows about that? Or about the fact that US military analysts write that one “purpose of Israeli nuclear weapons, not often stated, but obvious, is their `use’ on the United States,” presumably to ensure consistent US support for Israeli policies?
Probably in most of these cases the media didn’t know enough even to investigate, or didn’t have any incentive to, which just presses the question back one step farther. For what it’s worth, in all of these cases … the attacker was considered to be serving US government interests.
