Thank God they are. They are doing it to preserve their own existance and to avoid the ISlamic madmen from obtaining that power.
Iran must be stopped, by any means necessary, from obtaining such a weapon. The US needs to make this abundantly and crytsal clear...to Iran directly as well as indicating to any nation that would assist them in doing so that they will pay a terrible price for so doing.
Why can’t Islamic madmen have nukes, too? Just because they’re liable to use it like a dagger at a kasbah? That’s racism and Apartheid.
