IMO All of the sanctions on Earth will not deter Iran's regime. North Korea couldn't be much more isolated than it already is, yet, that isolation hasn't deterred Kim's regime from its nuclear ambitions. And in all probability, China (and others) will simply increase their business with Iran to offset any of Iran's losses from the West. Even if Russia agrees to sanctions, it won't matter.
