What does that have to do with anything?
No matter who supplied the reactors, Israel would be threatened. Nuclear power is good for very little except making bombs. Nuclear electricity can not compete on the open market with anything. The ONLY reason that Iran has nuclear plants is to make nuclear bombs. Iran has already announced its intention to attack Israel, in case you did not notice. If there is not a coup in Iran fairly soon, Israel will have no choice but to attack Iran first. It may use iron bombs, but it may use its own nukes instead. It depends.
