> It's a grotesque display of war actual war crimes

Even if we assume that number is accurate.

Dead children dont neccesarily equal a war crime, it depends on context. E.g. if the children are combatants, not a war crime. If it was collateral damage, not a war crime (assuming that it wasnt reckless, there was a porportional military advantage, etc. lots of details here).

To be a war crime requires a bunch of stuff beyond just children dying.

To be clear, its still a tragedy.

> More than in any other recent war

https://en.wikipedia.org/wiki/Yemeni_civil_war_(2014%E2%80%9... says more than 85,000 children have died in the yemen civil war, so that's obviously untrue that its more than any other recent war. And that was the first war i checked.
