If it wasn't genocide, then the world would have an easier time supporting them. Israel has used their "defense" forces since the beginning to attack, disable and displace ethnic Arabs living in their claimed territory. They did it in the 40s and 50s, they did it through the 60s and then again in the 80s, and in the 90s they did it once again with the Golan Heights law. It's a genocide as we know it, unless you're of the Chomsky brand of denial a-la Bosnia.
Ordinarily, nations with a preeminent claim to "living there" have a stronger defense when they say they were protecting themselves. Israel has a particular tenacity for moving their borders arbitrarily, ignoring international outcry and playing victim when the natives fight back.
The alternative view is that in every single war the neighbouring enemy had openly declared that it wanted to destroy the whole of Israel proper, and either attacked or were massed on its borders waiting to attack.
No "natives" have a right to pursue terrorism in order to grab land (Israel proper) back that they lost through war and international consensus, which is what the Palestinians and other neighbouring enemies have been doing for in the 30s (Hebron massacre 1930s, Sefad massacres 1830s), 40s (multi pronged war on the just-declared Israel), 50s (1953), 60s (1967), 70s (1973), 80s (Lebanon, PLO), 90s (intefada), etc etc
This is not defence by the natives, this is the grandchildren of a small population proving time and time again that allowing them independence will simply increase their continuous existential on threat to the established neighbouring state.
I decry the 25,000 civilian deaths in Gaza and even the 15,000 terrorist deaths but I put the blame for this on Hamas for committing true genocidal acts against Jews and then turning civilians into legitimate (proportional to the threat) military targets, and for the international community for very misguidedly hammering Israel with 10x times ferocity that they reserved for the terrorist who instigated this war.
