And, look at how the Arabs treat the Palestinians...

These descendents of refugees, speaking the same language, and having the same religion, are not allowed to be resettled...

It is a cynical but time-honoured practice in Middle Eastern politics: the statesmen who decry the political and humanitarian crisis of the approximately 3.9 million Palestinians in the Israeli-occupied West Bank and in Gaza ignore the plight of an estimated 4.6 million Palestinians who live in Arab countries. For decades, Arab governments have justified their decision to maintain millions of stateless Palestinians as refugees in squalid camps as a means of applying pressure to Israel. The refugee problem will be solved, they say, when Israel agrees to let the Palestinians have their own state.

Yet in the two decades since the end of the Cold War, after two Gulf wars, and the rise and fall of the Oslo peace process, not a single Palestinian refugee has returned to Israel – and only a handful of ageing political functionaries have returned from neighbouring Arab countries to the West Bank and Gaza. Instead, failed peace plans and shifting political priorities have resulted in a second Palestinian "Nakba", or catastrophe – this one at hands of the Arab governments. "Marginalised, deprived of basic political and economic rights, trapped in the camps, bereft of realistic prospects, heavily armed and standing atop multiple fault lines," a report by the International Crisis Group (ICG) in Lebanon recently observed, "the refugee population constitutes a time bomb."

The fact that the divided Palestinian political leadership is silent about the mistreatment of the refugees by Arab states does not make such behaviour any less reprehensible – or less dangerous. Some 250,000 Palestinians were chased out of Kuwait and other Gulf States to punish the Palestinian political leadership for supporting Saddam Hussein. Tens of thousands of Palestinian residents of Iraq were similarly dispossessed after the second Gulf war.

In 2001, Palestinians in Lebanon were stripped of the right to own property, or to pass on the property that they already owned to their children – and banned from working as doctors, lawyers, pharmacists or in 20 other professions. Even the Palestinian refugee community in Jordan, historically the most welcoming Arab state, has reason to feel insecure in the face of official threats to revoke their citizenship. The systematic refusal of Arab governments to grant basic human rights to Palestinians who are born and die in their countries – combined with periodic mass expulsions of entire Palestinian communities – recalls the treatment of Jews in medieval Europe. Along with dispossession and marginalisation has come a new and frightening turn away from the traditional forms of nationalism that once dominated the refugee camps towards the radical pan-Islamic ideology of al-Qa'ida.
