If I were Israel, I would have not invaded Gaza, which would have resulted in far fewer civilian casualties, and also would have ended the strikes by Hezbollah.
Also, if you look at the data on attacks by Israel against Lebanon, they are disproportionate, Israel launching 10x more airstrikes, even going so far as to level entire city blocks of apartment buildings in Beirut. I remember just on the first day of attacks by Israel against Lebanon, over 1000 civilians were killed. Also Israel refuses to vacate southern Lebanon after a ceasefire agreement, and continues to violate the ceasefire. Just in the last 24h, Israel has bombarded 4 different locations in Central Lebanon with airstrikes. If I were Israel, I would simply stop acting as a fanatic aggressor with no regard for human life.
> If I were Israel, I would have not invaded Gaza
During the war Israel was attacked from the territories of Gaza, Lebanon, the west bank, Iraq, Iran, and Yemen. All of these were unprovoked, except maybe Iran. All by parties openly calling for Israel's destruction.
Gaza had invaded Israel, killing 1200 and kidnapping 250.
What do you think the above attackers would do if Israel showed there was effectively no retaliation for doing something like that? You are asking Israel to commit suicide.
> If I were Israel, I would simply stop acting as a fanatic aggressor
Israel was attacked first by each and every party above (except maybe Iran), beginning with the Hamas attack.
> with no regard for human life.
In nearly every bombing in Lebanon, and most bombings in Gaza, Israel preceded the attacks with leaflet, social media posts, and phone calls calling people to leave the area. It has achieved the best civilian-combatant death ratio of any urban war in modern history. How does that show no regard for human life?
The military dynamics of the Israel and Hezbollah conflict are an indictment of Israeli's Gaza campaign. When Israel is clear-eyed, strategic, and effective at confronting a serious military adversary, it looks like the Hezbollah conflict: ultra-targeted rapidly disabling strikes. That Israel instead systematically leveled an entire civilian metropolitan area to combat Hamas makes the the claims about the Hezbollah strike more damning, not less.
