If you were going to go after Iran's nukes, how would you do it?

I’m pretty sure they have secret facilities buried deep under mountains in various parts of the country. If you were Israel, how would you go after these facilities? Would you use bombs? Would you use nuclear weapons? Would you go in on the ground? Would you smuggle in weapons in a clandestine way? Would you try to get the US to do your dirty work for you? Would you try to apply more diplomatic pressure?

Whatever you would do, please add more detail to your plan.
