Russia's Warning on Iran

Russia has issued a warning to the United States in reguards to threatening Iran when the Sec. Def. told a German newspaper that all options were still on the table. Russia would perfer that talks continue, in hopes that Iran would agree to cease enrichment within their boarders, thus allowing a joint venture between Iran and Russia to enrich uranium in Russia.

This is said to be a good thing, and on it's face I will agree that it is. It's good because the enrichment is no longer being done in Iran, but is being done in a country where the United States and other nations (such as the UK) have easier access to what is actually transpiring and can help to hold Russia and Iran accountable.

However, I am concerned because of the fact that it is Russia that is offering to do this. Russia and Ukraine already sold Iran weapons, some of which could hold nukes within them. It is no secret that there is an alliance brewing between Iran and Russia, be it publically or through backroom actions. That being said, what is it exactly that keeps Russia from helping Iran enrich uranium for a bomb? If Russia desires to "get her old glory back" then would not helping Iran to get the bomb and then sit back and watch Iran attack the US or Israel (thus drawing America into an additional conflict) be a step in the right direction? I do wonder...
