The Israeli's absolutely had a range of options open to them after the attack on Oct 7th, but this wasn't the point in question. It was for alternatives to the current course of action being used by Israel for the removal of Hamas. As they would be suggestions they couldn't be anything else other than opinions at this point.It's not an opinion that there was more than one response available to the situation for the Israelis. It's a fact.
I do have opinions about why they chose this particular course of action, and when I expound them I will say it's an opinion.
