They already have one.. have had for some time. Strike range of over 750 miles, making Isreal within easy reach. :stone
Wouldn't surprise me any to see them stirring up some real trouble, now that Ariel is in critical condition and the country is in the midst of power transfer.
Iran is getting pretty bold here lately. Snubbing it's nose at the entire global community.
Don't count on China or Russia to wag their finger at them, though.
