Most of them don’t like Israel anyway. So they Hope that Israel’s status will Change from existent to non-existent.
Lord, How can that be?
Suppose Iran nukes an Israeli target. Israel retaliates with several nukes. The rest of the Arab world decides it is time to settle with Israel once and for all. Obama decides to forsake Israel (a little hope and change there) and warns it against further use of nuclear weapons. The Arabs invade Israel and it is cast into a life and death struggle. If the Samson option is not used, Israel might be overrun. There is your hope and change.
I do not believe that Israel would be overrun and in the event, I do not believe they would withhold the Samson option. I also am ignoring divine intervention in this scenario. The one assumption here that I think is on the firmest ground is Obama’s stab in the back.
