"You warned everyone weeks ahead but you stopped doing so now so you're wrong"?!?!?!?!?
Are you serious? What more do you want from them? They did everything they could to alert everyone in Gaza that they were coming and the need to evacuate.
They're making their own safe routes, transferring thousands of civilians through them. You really can't expect more from an army, when its purpose is killing its enemies. Looks like they waste lots of time doing non-killing.
And the number of victims is terrible, but it's the price of war, and it looks like the Palestinian leaders are more than happy to accept those numbers. War is a 2 sided thing, and you only blame one - and the one which is doing literally all it can to prevent needless death. While the other side, which you think is just, is parading dead bodies and advocating for true genocide "from the river to the sea". What peace can there be with that kind of leadership.
History will remember this war like they remember WW2. Did Britain kill civilian germans? Lots. The number of german killed vs the number of British killed is humongous. Are they remembered as "merciless killers"? No. Because they were fighting objective evil.
So is Israel.
