They are definitely fearing what Israel is going to do, but Israel will likely do nothing more than kill a few Palestinians & try to make believe that they've done enough. & then the mask will drop & all will know that Israel is nearly defeated. Except for completely beaten countries like Lebanon, most Arabs already sense Israel's weakness & expect to be able to destroy it eventually. This will be confirmation to any Arabs who still had reservations. I predict that this will inflame anti-semitism like never before. Jewish weakness breeds anti-semitism.
The only good thing that can come out of it is that I know that Israelis will fight hard if their backs are against the wall. Maybe it's the only way for Israel to react.
Perhaps.
Don’t forget about the USS Cole sitting off Lebanon.
