My Opinion
Of course they are doing this, the Iranians and Arabs think that Israel is stupid and not going to know what they are doing, but they haven't woken up to the idea that we are a living in the 21st century and they are still living in the deep dark ages with age old military tactics that do not work anymore... Their military tactic is to bark as loud as they can and assume that their enemy will run with his tail between his legs, I mean really, get over it and catch up with the rest of the world...
The more pressure these people put on Israel, the stronger Israel becomes, we just work well under pressure... :)
