Could we face WW3 if Israel decides to attack Iran?

the israelis are not stupid. believe me when i say they are in contact with iran through other channels besides cnn. they are not going to initiate any war unless they feel their national identity is threatened. so far there,s been lots of cheap talk. iran had also been thru a nasty war. when you,ve seen the elephant, you are reluctant to go there again without severe provocation.
