Arab "occupation" abuse has gotten a free pass.

Obama disclaims knowledge of things that happened before he was an adult ( see his defense against the Bill Ayers association ). Since his transcripts are unavailable, we don't know if he ever took courses in history. In this case, most people don't know the extent of ARAB persecution of Palestinians. ( Or why...perhaps they're a "stiff-necked people.")
Scenes From an Arab Occupation
...we faulted President Obama and his Cairo speech for ignoring Arab states' responsibility for the continuing plight of the Palestinians. One point we made was that the president had conflated the Palestinian "dislocation" following the birth of Israel and the Arabs' war on it with the Israeli "occupation" of the West Bank and Gaza after the Six Day War, two decades later--not even mentioning that the disputed territories were under Jordanian and Egyptian occupation during the interim.
One reader wrote to us and gamely insisted that ...his comments should be read as referring to the Arab occupation as well. Maybe, but we'd be less surprised to learn that he doesn't know about the Arab occupation, which is usually left out of the popular narrative....Jerusalem Post has...op-ed by...Eliezer Whartman, who visited Gaza just after the Israelis took over and "encountered a territory that bore stark witness to Egyptian aggression, callousness and inhumanity." He describes the conditions that prevailed under Egyptian rule:
There were no elections. A puppet government...In 1965, even this façade of local autonomy collapsed when the Egyptian army dismissed the legislature.
The secret police probed everywhere. No one was immune from sudden arrest and unlimited imprisonment without trial or, at best, a secret trial. The jails were always full and torture was common. There was official censorship of the press and mail, and telephone lines were regularly tapped.
For nearly 19 years, the inhabitants...were prohibited from leaving their homes from 9 p.m. until dawn on pain of death. This curfew was enforced by roadblocks. Men between 18 and 40 were prohibited from traveling to Egypt unless they were fortunate enough to secure permits. If they failed to return at the expiration of their permit, the military authorities took steps against their families.
The Egyptians seized property at will, while refugees were prohibited from owning land.
Of course, this was a long time ago--but the founding of Israel was even longer ago, and those who style themselves "pro-Palestinian" are happy to nurture grievances from that era while excusing Arab regimes for perpetuating rather than seeking to ameliorate the Palestinians' plight. Whartman quotes from an interview Egypt's deputy Gaza governor gave to a Danish newspaper in February 1967:
Question: Why not send the refugees to other Arab countries? Syria would no doubt be able to absorb a vast number of them. Are you afraid that national bonds with Palestine will be loosened, that the hatred against Israel will vanish if they become ordinary citizens?
Answer: As a matter of fact, you are right. Syria could take all of them, and the problem would be solved. But we do not want that. They are to return to Palestine.
UNRWA [the U.N. Relief and Works Agency] reported in 1956: "One of the obstacles to the achievement of the General Assembly's goal of making the refugees self-supporting continues to be the opposition of the governments in the area."
Ralph Galloway, an UNRWA official who quit in frustration, observed bitterly: "The Arab states don't want to solve the refugee problem. They want to keep it as an open sore, as a weapon against Israel. Arab leaders don't give a damn whether the refugees live or die."
Plus ça change. President Obama, like many before him, is deluding himself if he thinks he can resolve the problem without acknowledging the Arab dictators' interest in perpetuating it.
