It most absolutely is not and I struggle to believe you can build a valid argument that links bombing school children as necessary for the fall of Iran’s government.
How you win a war, especially one as lopsided as this invasion is, is as important as winning. I cannot so easily sleep at night knowing we are committing horrific atrocities during an invasion we chose to launch against a country thousands of miles away with zero military capacity to harm us here at home.
Thats not the point though. There is no reason for either party to respond proportionally in a war. Going to war against an equal weight class as idiocy, sun tzu figured that one out forever ago.
Hand wavy “that’s war for ya” nonsense isn’t appropriate for a serious discussion of ethics. Especially when discussing bombing a school.
Unfortunately for everyone, now the US and israel killed a bunch of kids, and reinforced that precedent for others with these sorts of flimsy justifications, *and* everything will be the same or worse in Iran, especially for civilians. So lose-lose-lose.
> Even if Israel is mostly responsible for that [conditions in the Gaza region of Palestine] I think conditions will improve if Iran cuts Hamas off.
We can already see the outcome of that in the West Bank region of Palestine: no hamas, yet israel still exercises ultimate control via violence, and keeps oppressing and killing Palestinians and taking or destroying their stuff with impunity, especially as of late.
There's no indication israel would be more generous to Palestinians in the Gaza region of Palestine if hamas wasn't there. Palestinians in Gaza see what israel does to Palestinians in the West Bank, and want no part of it. Who can blame them? It's sick.
Killing children is a war crime, and not an inevitable part of war.
The list of today's remaining colonies is short enough[0] that it is worth considering whether decolonization was "an idea that reached its time" in the late 20th century ; and given that there are examples of peaceful revolutions (eg India and West Africa) it is worth asking whether more places could have undergone peaceful transitions, and whether the cost in human lives and atrocities born within a decade of war doesn't outweigh the cost of the colonial system dying by itself within the same order of magnitude of time.
But then again, I think you're veering us somewhat off-topic as I'd consider a "colonial freedom war" to be a revolution (the people overthrowing their overlord) which is quite different from the topic at hand here, war between nation-states.

And it's not about whether it's "okay".
