OK, so it is law. Damn definitions!

Agreed, Iranian officials have repeatedly stated that they'd want to exterminate Israel. With Pakistan developing the way it does this doesn't really seem unlikely to eventually happen, too.
Also, I believe that all this talk about exterminating Israel is mostly directed at the Iranian population (and the Lebanese Hizbullah and the Palestinians). With a youth unemployment rate as high as 25 percent they have to keep them entertained and in line somehow. And nothing unifies better than a common enemy.

...but then, if they sought peaceful existence rather than extermination of others, they wouldn't be pursuing these weapons in the first place.
