Everything you said is wrong. Egypt is trying to let aid through, Israel has repeatedly bombed the roads in each time they’re fixed; preventing aid. Also, as you so aptly pointed out, it’s war. The first thing a functioning country does in war is ration food so the soldiers can stay fed; even if it costs civilian lives. This has happened many times. That Israel is purposely starving civilians knowing full well it won’t affect the soldiers, just for propaganda, is frankly evil.
