to full GCC membership are steep. Reportedly, Kuwait, still bitter over Yemen's support for Saddam Hussein during the first Gulf War, has blocked further discussion of membership. Meanwhile, Yemen needs to export thousands of its workers each year to the Gulf in order to alleviate economic burdens at home. Foreign remittances are, aside from oil exports, Yemen's primary source of hard currency. Arab–Israeli conflict Yemen has usually followed mainstream Arab positions on Arab–Israel issues, and its geographic distance from the conflict and lack of political clout make it a minor player in the peace process. Yemen has not established any bilateral mechanism for diplomatic or commercial contacts with Israel. The Yemeni Jewish community (300 members) continues to dwindle, as many of its members emigrated to Israel decades ago. On December 11, 2008, Moshe Nahari, a Jewish teacher, was murdered in a market in Raidah, home to one of the last Jewish communities in Yemen. After the attack, President Saleh pledged to relocate Yemeni Jews to the capital.

In the spring of 2008, President Saleh attempted to broker a reconciliation agreement between the competing Palestinian factions Hamas and Fatah. During a March meeting in Sana'a, Palestinian representatives from both groups signed a declaration (the Sana'a Declaration) calling for the creation of a national unity government, but the talks fell apart over the issue of Hamas's role in a unified Palestinian Authority.
