Just thinking.

Ok:

Israel is in Lebanon (fact)
Syria is afraid. Tells Hizbullah to stop (JPost)
Syria is afraid of getting slammed (me)
Iran says not to attack Syria or retaliation is promised (Haaretz)
Iran secretly wants Israel to attack Syria (me)
If Iran attacks Israel, US attacks Iran (me)
If US attacks Iran, WW3 has an open door (me)
Iran and others want to see the US and Israel fight the Muslim world for the final showdown (me and a lot of other people)

I dunno, just thinking.
