Israel is supposed to have the best border/customs procedures on the planet. I wouldn't think they (Iran) could get something of size inside that country, especially since Isr is, off and on, at war with about 7 different countries... Isr would always be on high alert. Also, would Iran detonate somewhere where the fallout could reach back into Iran? I wouldn't think so, but maybe the leaders are willing to live underground for the better part of a year and come back up to a decimated country. I'm assuming they have no delivery system other than a ground-based vehicle.
