Sure I understand how Arab or Muslim countries might vote against Israel reflexively, but it's not just them, it's almost the entire world.
Go look at this list of Israel related General Assembly resolutions in 2025:

The typical vote is like 142-6. The Israeli claim is that almost the entire world are a bunch of anti-Semites that hate them for who they are. Perhaps it's not who they are but what they are doing.
