> Those who embrace this view fail, however, to explain how it aligns with the inherent right of self-defense
That's quite a rich comment in light of the Dahiya doctrine. It's times like these that I'm glad HN won't let you delete comments for posterity's purpose.
> what scope of military action is necessary to secure the safety of the Israeli population from the Hamas (and Palestinian Islamic Jihad) threat emanating from Gaza?
When you define it like that, literally any military action, up to and including the destruction of all of Israel and it's inhabitants (a-la Samson option) is excusable. The "we have to go to their country and kill them all to protect our way of life" mindset is the fascistic seed of genocide.
Nobody is going to play by that definition. You're delusional if you think the scope of a perceived threat justifies the intensity of an actualized retaliation - it's a misunderstanding of strike warfare. The laser-focus on total war has impaired the IDF's ability to respond to precision threats in a dignified way. It's impossible to argue that Hamas hasn't exploited this obsession, and it's destroying foreign support at an unprecedented rate. You can only massacre so many Qibyas before your government's long-term strategy comes into question.
> Indeed, it is likely that historians will question whether Israel exercised unnecessary restraint up to this point
Here's a thought-exercise for you; how does the world look at America for developing the nuclear bomb? Do you think they love us, for subjugating the world under the ironclad-rule of a nuclear age? Do you think historians criticize America for showing too much restraint in Nagasaki?
Food for thought, may it nourish your starving soul.
