Are Arabs and Israelis starting to work together against Iran?
There's continued talk of an Israeli air raid on Iranian nuclear weapons facilities, but no action. Israel does appear to have formed an informal alliance with several Arab states (Egypt, Saudi Arabia, etc.) against Iran. The Arabs cannot officially admit to an alliance with Israel, because of decades of state sponsored anti-Israel (and anti-Semitic) propaganda. Some of this propaganda is being shut down, quietly. Something is going on here.
Reality trumps rhetoric.
