This wouldn’t surprise me. Israel has not attacked for a reason. What would be the advantage in waiting? Israeli intelligence probably knows the truth.
Nukes may be a factor but the real reason is there is nothing to bomb. The facilities are buried deep underground under tons of rock. You lob bombs on mountains and you would never know if you were successful without soldiers on the ground to check it out. This situation is not like the 1980s where they could take out an above ground facility . The only way to stop Iran's program unfortunately is with boots on the ground and even then it would be dicey.
