And ironically, a lot of the Western Left that despises Israel in OTL, would despise the Palestineans instead. Not least because McCarthy liked them. Not to mention that with the Soviets as their main patron, *Israel would probably have to have a more secular and socialist internal politics.
Which strengthens the Democratic Party of the US after the late 60s--as their stance as the party of doves, the non-anti-Communist party, and all that no longer conflicts with Jewish support. (Assuming butterflies haven't changed all that.)
On the European Left, Palestineans are not seen as victims of imperialism, but as religious reactionary neo-Nazis. In this world, it's a LOT easier to claim that Christian fundamentalists and Muslim fundamentalists are exactly the same thing, and that both are Nazis.
The UN General Assembly may end up passing a resolution that Anti-Zionism is racism, to stick a thumb in the US's eye.
Note that none of this requires that the *PLO be much different.
Well, they might also despise them for a different reason: having US weaponry instead of Soviet is not going to make Yasser Arafat a good general. He was a lousy, terrible war-wager who never won a war or even arguably a battle in his life (depending on how we categorize Karameh the credit, if it goes to Arabs, should be to the Jordanians, not Fatah). He'd be even worse than Rhee and ARVN in this scenario and further perpetuate the question of why Soviet puppets beat up on US proxies. Depending on the cultural butterflies, this could actually backfire horribly on the USA.
OTOH, if the USA's that involved with the PLO, we may never hear of Arafat and instead be speaking of that bungling idiot Shuqeri.
