I think boomers are also a bit more unconditionally supportive of the state of Israel for some reason as well. Perhaps (and this is my speculation) they were more propagandized than younger people whom have better access to global communication and cultural exchange, and were therefore more Arabophobic on average.
Also, Israel is the US’s military foothold in the middle east, so it’s there as power projection to the oil-rich countries in the vicinity.
Perhaps this is true but if he leaves office, the genocide will continue apace. It may ebb but it will always be center to Israel’s project. There is a lot of internal conflict in Israel and fascism is boiling over.
