God no, not disagreeing.
But to show you the hell of this war:
I have no doubt that Hamas would use teenagers in a different type of war, but not this one.
This is that war. Why would they change now given it's been their strategy all along. Hamas historically has long used their civilians as "shields" in a very calculated manner. Given most of the population are children, then children will bear the brunt of this callous decision. Any group which casually trains its fighters to say "drop your pants" in another language really do not care about anything but specific outcomes.
BUT...
Israel is keen to rush ahead in this challenge and trap Hamas has set - no matter what their PR people are stating. They are fighting the war Hamas planned from the beginning.
And in so doing the tactics they are using are still thud and blunder in nature as Hamas expected. My complaint is they knew the nature of the next war in Gaza was going to be exactly what is going on and they did did nothing mostly because it was noise to Netanyahu's desired outcomes. My snark was the IDF became the "boot" squad of the West Bank settler program and did not focus on what was likely the next war which required very precise tools and tactics to handle Hamas' indiscriminate use of civilians. Or TL;DR - the politicized use of the IDF in the West Bank destroyed the "professionalism" of the IDF. Israel is much more in danger now than in 1973 because of Netanyahu's strategy. I am hoping the Israeli's understand this sooner than later and come to their senses and bring in a government which is more pragmatic and less ideology based.
This is factually a disaster for civilians - but I can not blame just one side for this - it takes two to play here and neither truly care about the civilians.
On Edit:
Hamas wants to destroy Israel - they do not care if they destroy Gaza in the process. Similarly, Netanyahu wants to destroy the Palestinians in the vague hope it leads to a greater Israel - he does not care what that does to Israel
