Are you familiar with the doctrine of competing harms?
From your response, I deduce your answer is "no", and that you would have no problem with an Israeli assassination team killing somebody on US soil if that person was against some Israeli interest.
That being covered, would you also sit still for the assassination of a Congressman or govt official who advocated a policy that made Israeli officials seriously uncomfortable? How about a US citizen who advocated ending foreign aid for Israel?
You are sufficiently familiar with my positions on FR to know that I'm no fan of Islam. I dislike the idea of foreign hit teams in the US, wherever they come from. I'm sure the Israelis would be uncomfortable if the US sent Delta force teams into Israel to capture Pollard's Mossad handlers and get an accounting of what US secrets he passed on, and who the secrets were forwarded to
