There’s no doubt in my mind that Hamas, Hezbollah, the Houthis, etc. etc. would, given half the chance, genocide Jews in Israel.
But I think part of genocide is having the power structure to actually accomplish that level of violence and they just aren’t capable of it. Individual ATROCITIES? Sure, that’s in their reach. Assassinating an entire people? They just don’t have that capability.
If you look at an American example… the Americans had the capability and desire to commit genocide against Native Americans.
The inverse? Massacres, sure, genocide? Not so much.
