Golda Meir didn't actually deny the existence of Palestinians. She saw that as referring to all those living in Palestine before Partition, Jewish Palestinians and Muslim or Christian Arab Palestinians, pointing out that until 1948 she'd been Palestinian herself, with a Palestinian passport.

There was a Zionist song with the line "Fight, fight, fight for Palestine" someone posted on the Cat years ago.

There'd be a lot to be said in favour of thinking in terms of Partition and Anti-Partition in the context of this conflict. If a two-state solution is the best that could be hoped for (very barely at that) in the present nightmare, that is very much a second best. In the long run an end to Partition must be the goal. It'd be far better if the term Palestine could be reserved for the whole region, with another word for the West Bank and Gaza entity.
