We have casualties both civilian and military of about 17,000 dead in Gaza. Agreed its terrible. We also had about 30,000 casualties in the recent Assad-Alwaitie civil war in Syria. The place with the "Line in the Sand" We here in The US did not hear much grief and anguish offered for those Syrian dead.
The present situation in Middle East Palestinian is like many other treble situations in the past, it doesn't matter how worse it is! Biden thinks about his presidency's vote, not thinking about the genesis in Gaza, as well as Netanyahu who wants to be in wolverine in Isreal, so, no matter how worse is the situation in Gaza.
Neither it's a "Holy War" Both are completely obsessed with their religions they can't accept living together.
