Here is a very good Washington Post article about Israel, and its policy of targeted killings.

I’ve said before that I favor assassinations over wider wars (which kill more, and less guilty, people).

It’s a very important tactic to help prevent innocent deaths. The
Israelis practice it very carefully and should be respected for their
moral approach to defending their people while taking great pains to
avoid as much innocent death as possible.

Unfortunately, it isn’t possible to avoid all of it.
