There is no ethnic group known as Americans either. Is there a point here?
There is a sovereign country known as America. Those citizens of America are Americans.
There is no country known as Palestine. Indeed, Israel encompasses most of the geographic territory known as Palestine, so, technically, Jews are Palestinians.
However, even Arabs know Palestinians are a fiction...
Arab commentator Azmi Bishara
“Well, I dont think there is a Palestinian nation at all. I think there is an Arab nation. I always thought so and I did not change my mind. I do not think there is a Palestinian nation, I think its a colonialist invention - Palestinian nation. When were there any Palestinians? Where did it come from? I think there is an Arab nation. I never turned to be a Palestinian nationalist, despite of my decisive struggle against the occupation. I think that until the end of the 19th century, Palestine was the south of Greater Syria.
This was an interesting choice to post to support your premise. It seems you have not taken the time to find out who Bishara actually is, and what his politics actually are.
Bishara is an Arab Christian Israeli citizen, born in Nazareth. He is one of the founders and leader of the NDA-Balad political party (an Israeli Arab party.) He was elected to Knesset, and ran for Prime Minister before withdrawing from the race shortly before the election.
Israel charged Bishara with various criminal offenses after he visited Syria and Lebanon several times and expressed his support for Hezbollah. He and his NDA-Balad party have been accused by the Israeli attorney general of seeking to "destroy the Jewish character of the state and supported the armed struggle against it.”
He has since resigned from Knesset and is currently living abroad.
As for this disembodied clip, taken out of context:
Bishara is a pan-Arabist. This clip is from a speech he gave expressing his support for a pan-Arabic state based on the historical model of Greater Syria, which included Syria, Palestine, Lebanon, and Jordan.
In fact, Bishara has referred to “Palestine” and “Palestinians” many times, and has written extensively on his opposition to the Israeli occupation of Palestinian land (as well as Lebanese and Syrian territory) and been an outspoken critic of the Israeli government’s oppression of the Palestinian people.
But you could see all this for yourself, if you would only read some of his published writings instead of taking carefully cherry-picked snippets off dubious websites which don't tell you the full story.
I can't post links yet (how annoying!) but here are the titles of just a few articles written by Bishara for al-Ahram Weekly, the English-language edition of EgyptÂ’s largest newspaper. They are teeming with the words "Palestine" and "Palestinians":
Israeli games again
Strong in spite of themselves
Ignorant thieves
You can find them easily with a Google search of his name and the title of the article.
