Are you asserting that Egypt is zionist? The Palatinian Liberation Organization? All of there states have said that Israel has a right to exist. Passed resolutions.
If so, then what value has the word?
Zionism has changed over time. Israel exists, is going no where, and only weirdos think Israel should vanish.
However many will espouse an end to zionism today, which typically and effectively means no more expansion into modern Palastine, and a 2 state solution.
On what evidence is this claim based on?
Both peoples have existed in the Middle East, and in that area for thousands of years.
I find few people that think Israel shouldn't exist. Do you have any sort of surveys, indicating that most people on the planet think Israel should bot exist?
It's a very weird assertion.
