When they hit Osirak in the 80s and the Syrian facility a couple years ago, they weren't waiting around for the nukes to be deployable. They also didn't care what anyone else thought about it.
That was true, but to say it as simple as possible, that was then, this is now. I wish they could do just what they did then, but I am not sure about it. They could conceivably get away with exact, precise strikes aimed solely at the facilities-which would have to be done perfectly. But they are walking on landmines here.
