There are no easy solutions here. Hopefully Israelis (both IDF and politicians) find the right choice/ trade-off between a need to retaliate harshly and a danger of loss of lives and escalation… one thing people should avoid is pushing decision-makers into a public-opinion boxes in either direction. Hopefully, they make decisions based on sober analysis rather than emotional/political pressure.
For example, it is easy to say that harsh response will regenerate deterrence (at a tremendous cost). But, maybe, a limited operation showing destructive capabilities combined with stronger allied support, will also work? Would someone be pressured to go on offensive to placate supporters or silence opposition? Let’s think how to reduce this pressure.
