Strategy Page on the paradoxical Arab view of Palestine as worth fighting for, but actual living Palestinians as less-than-welcome pests (or worse):
While most Arabs will admit they hate Israel, they will also deny that this has anything to do with anti-Semitism and has everything to do with the Palestinians. This is not true, as Arabs have long demonstrated a hostility towards the Jews, something which is part of their religion. It’s in their scriptures, the stories of how Jews refused to support Mohammed, the founder of Islam. Long held grudges are popular in this part of the world.
Meanwhile, there are many more recent reasons for Arabs to dislike the Palestinians. When the state of Israel was established in 1947 there began a series of bad decisions by Arab governments that are setting records for failure. Although the UN tried to broker the creation of Israel, Arab nations misjudged their own power and told Arabs in Israel to flee their homes, so that the Arab armies could come in and kill all the Jews. When that didn’t work, the Arabs refused to absorb the 600,000 Arab refugees, and continues to treat (actually, mistreat) them as refugees. At the same time, the Arabs expelled 600,000 Jews who had been living among them for centuries. Most of these Jews went to Israel and become Israelis, and prospered.
Thus began decades of hostility between Palestinians and the rest of the Arab world. The Palestinians that fled to Lebanon proceeded to trigger a 15 year long civil war (1975-90) that devastated the country and left in place a Shia militia in the south (Hezbollah) that prevents the country from being truly united. The Palestinians that fled to Jordan eventually (1970) staged an uprising against the king, and were defeated and largely expelled. The Palestinians that went to Kuwait welcomed the Iraqi invasion of 1990 because Saddam Hussein had always been very loud about wanting to destroy Israel. When Arab and Western troops tossed Saddam out of Kuwait five months later, the Palestinians were forced to flee the vengeance of the Kuwaitis. The Palestinians that went to Iraq also had to flee in 2003, because they had helped Saddam terrorize the Shia and Kurdish majority and were, well, you know the story.
