Mediator of Palestine armistice--awarded the Nobel Peace Prize?

Nobody has yet been awarded a Nobel Peace Prize for brokering an armistice between Israel and Palestine, although former Israeli PM Yitzhak Rabin and Palestinian leader Yasser Arafat were nominated for it back in 1993 (in the event, the Prize that year was won jointly by Nelson Mandela and South African President F. W. DeClerk). A Palestinian doctor, gynaecologist Dr.Ezzeldeen Abu al-Aish, whose 3 children were killed during last Autumn's Israeli attacks on Gaza, has been nominated to receive this year's Nobel Peace Prize, although it's not yet certain that he will win it.
A former Prize winner, Irish woman Mairead Macguire (who won the award in 1976 for her work to bring peace to Northern Ireland) was shot and wounded whilst visiting the West Bank last year in solidarity with the Palestinian people. There have also been calls for last year's Nobel Prize winner, the Finnish diplomat Marrti Ahtisaari (who was given the award for his work in brokering an end to the conflict in Bosnia in the '90s), to be called in to help broker a ceasefire between Israel and Palestine.
