Both Egypt and Jordan have signed Peace Agreements with Israel (more of a cold peace than a warm peace), but the Arab League as an organization has been hostile until recently.
According to the NY Times website:
Foreign ministry spokesman Mark Regev said the visit was historic.
''This is the first time that a delegation is coming here under the auspices of the Arab League,'' he said. ''In the past, the Arab League has opposed dialogue, normalization and any contact with Israel and this is the first time the Arab League has authorized a delegation to visit Israel.''
Now, they are offering a peace plan. Israel will not accept a plan that includes full withdrawal from East Jerusalem (which includes the Old City and large numbers of Jewish neighborhoods but also contains the bulk of the Arab population of the city) and the population centers of the West Bank. Still, Israel will be forced to respond and hopefully a real negotiation can resume.I am hopeful that peace is one step closer than before. May it come speedily in our day!
