There are a lot of reasons why right wingers and all sorts of supremacists support Israel. It's been baked into their political movements for half a century + now. You've got the christian dominionists, who want Palestine to be jewish as they see it as a requirement for the end times. You've got anti semites who enjoy both the fact that Israel is killing people who they hate even more (muslims), and that Israel is doing it far away from 'The West'. And you've got reactionaries who simply stand against anything they perceive to be a 'left wing' project.

What ties every one of these groups and others is the idea of good jews and bad jews. Good jews are israelis, as they are 'ethnonationalist' and carry out policies they wish to implement in their own countries. Bad jews are socialists, liberals, and left wingers. Whenever right wingers use the word globalist they harken to this supposed divide. It is only the hardcore anti semites who buckle the trend a bit and believe that, actually, all jews are globalists and the jewish conspiracy is that 'white countries' are not allowed to follow the same policies as Israel.

It's like that twitter post succintly put. People like Elon Musk will eventually reach an agreement with the israeli lobby. It's ok to be anti semite, as long as you don't criticize israeli apartheid.
