There simply aren't justifications for using starvation against civilians, calling them animals and calling for their extermination, while IDF soldiers make videos rifling through the belongings of Palestinians to mock them, talking about colonization. "They" (Israeli hard right etc.) always wanted to take the land, so using the crimes of Hamas as an excuse to do just whatever, for just targeting infrastructure to make Gaza unlivable, as they so proudly describe in interviews, while repeating how it's all just self-defense is just too transparent.
> it's clear that this would have been a lot worse for Israel if the blockade wasn't there
You think? As they say, there is nothing scarier than a man without hope, and nobody is complaining about not letting weapons in. At least I am not.
There is the cost to Israel. You cannot commit and justify atrocities, dehumanize other humans completely, without getting deeply damaged yourself. As Chris Hedges wrote about comraderie (versus friendship), it feels great in war time, it's a high, for a while, but the comedown is really depressing and lonely.
And then there is the damage in the eyes of the world, which will keep trickling in for many years. The US, UK, Israel and Germany have no credibility right now except to each other and the usual vassals.
