Were the Russians really surprised by Iran's Secrete Nuke Site?

I'm going to go out on a limb and say, "defiantly, maybe" .

The Russians seem to greet the news that Iran had a nuclear site that has been thus far secrete with an angry statement.

So are they really angry? Maybe.

Actually, Russian anger over Iran having a secrete program fits nicely with my thesis that Russia has more to fear from an Iranian nuke than America does. So, if the Russians had been in contact with Iran about its nuclear sites thus far and perhaps were somehow sure that the Iranians either were not going to weaponize or were otherwise on a tight leash, then the revelation that Iran had secrete site would scare them, because it means that Iran felt the need to hide their real intentions from the Russians as well as the Americans and everyone else.

Of course the Iranians feel the need to hide this site from the Russians, they have more to fear from Russia than from the U.S.
