Is not really surprising if they didn't. Israel did sure not attack the first building out of thin air, Israel might be aggressive, but not stupid.
But I fail to see how Uranium can be considered a nuclear weapon threat... while the USA used it in a single design, a nuclear weapon made of Uranium weights ten times more than a nuclear weapon by Plutonium - a big problem if you are limited to small launch vehicles. And plutonium production is a pretty clear sign of nuclear weapon goals as the many problems you get with it are making Plutonium unattractive for civil reactors.
Also, I notice some sort of media psychology on me, when reading about the real crimes of Syria and have the rather legal nuclear ambitions of Iran in the same article, despite being actually not related at all (Despite the reports being released by the IAEA on the same day).
Just as reminder: There is no international law denying the access to civil nuclear power... And Iran is sure no third world country with over-sized military and führer cult, or a supporter of terrorism. Who followed the news from Iran in the last weeks more carefully than usual, might notice that Iran suffers from Sunni terrorism as much as the rest of the world...
