Perhaps secretly Israel, United States, and Russia have made a deal - Russia knows Israel will attack. Russia moves forward with the deal already knowing Israel has been given the green flag to move forward. Russia stills make their money - pretends to be mad - USA looks the other way. Israel bombs the plant.
Russia then gets to sell everything back to Iran and make twice the money. :)
You need to take off the tin foil hat. Russia does not want Israel to bomb that reactor, it is in their best interest for Iran to go nuclear. One of the major selling points for the Kremlin is that Iraq is now a US ally, along with Israel, Jordan and sometimes Egypt. Russia doesn’t have much to bring to the table in the middle east anymore. This is all about to change.
