Kremlin values the NPT?

An interesting newsbite this week. Normally the media focuses on the headline grabbing soundbites, such as Clinton's 'warning' of the Revolutionary Guards supplanting civilian control of the Iranian government. 


What's most striking about this article is that Russia has suggested it may support further sanctions in light of Iran's increasing of uranium enrichment from 2%ish to 20%. It seems that Russia may yet be frustrated and tired of Iran, and does not want to see the Nuclear Non-proliferation Treaty (NPT) die. If Iran does become a nuclear armed power then the NPT will stand a good chance of becoming obsolete and a failure.


Or is it because Russia is afraid of the instability of the Iranian regime, and the nuclear equation makes any instability an immediate and important concern. Look at Pakistan.


Russia and China had always consistently played against Western sanctions on Iran. With Russia now tentatively agreeing with the West, will China follow suit? China has to learn eventually that it has great responsibility in global security as long as it continues to meddle in other countries' affairs. The situation will have to be resolved soon, as at 20%, Iran will have enough stockpiled enriched uranium to develop a few bombs.
