So what happens in the situations where Israel intelligence uses US supplied information as a basis for killing an American citizen?
Israel is pretty strongly focused on the Arab countries near it who are trying to destroy it. Not too many American citizens in those countries, and almost impossible for one to reach any kind of high position which would make them a target.
The parent was asking about executions though.
Plausible deniability plays a role here. Not all executions look like executions.
They'd want to recruit them - or maybe not, since an American Arab would never be trusted by other Arabs.
An American Arab would never be trusted enough to gain any useful information, so would not be of interest to Israel (not to recruit, not to kill).
Secondly, you do realize that many thousands of Arab families have family members -- brothers, sisters, sons, daughters, and cousins -- who are U.S. citizens? You think they suddenly don't trust them? Same goes for lifelong friends who immigrate to different countries. I'm sure this applies to almost all Arabs (and in fact all nationalities) who have family who are U.S. citizens, regardless of whether they are fundamentalist, secularist, pacifist, or ultra-religious.

It's not far-fetched to imagine Israel could do it too (with more traditional methods)
And here I thought the media was full of stories about the potential for U.S citizens to be radicalised and go to join jihadis.
