Like who didn't see this coming. It's been on the backburner moving right along for some time. Russia and China will let Ahmadinejad take center stage on this though...they are playing him to their advantage. In the end though....Russia will act with Iran and then turn on Iran, China will act alone...as always.
You could be very right. Historically, Russia & Iran have Always been enemies. Though now, there is mutual interest in being superficially united. The history of China & Iran is very different, more congenial & out of mutual respect - it goes back a long way. I believe, end of the day, China is more likely to be a long term supporter of Iran against the West than Russia.
In your post #28 you say: Obama is playing a role in it by weakening our nation from interfering. -- If the 'interference' is done intelligently & constructively, then it'd be great. Otherwise, it'll have the potential to be counterproductive even destructive to the U.S. & others.
Consider why Khomeini & Islamic insurgency were supported in Iran during Carter administration, under the banner of *democracy*. -- It was the Cold War at the time, with people such as Brzezinski and other Carter advisors worrying about the Soviet influence in Iran. Even as the Shah almost had a pathological dislike of the communists in Iran and their Soviet masters, who had been continuously trying to instigate trouble & even partition parts of Iran, namely Azarbaijan & other Northern provinces such as Gilan & Mazandaran along the Caspian Sea. The Shah even took very strong measure against the communists in Iran. Savak was mandated to watch out for those Iranians, in Iran & abroad, who had communist leanings or sympathies, and arrest & imprison them - they were seen as a real & dire threat.
However, the Shah's efforts weren't sufficient for Carter & Brzezinski. They foolishly thought Islam in the guise of Khomeini, whom Carter apparently once compared to Gandhi & a Saint, was more of a counter-strategy against the evil Soviets (the commies). It didn't quite work out as envisioned by Carter & his luminaries. Ironically, since 1979 Islamic revolution, it is the same Khomeinist (Islamic) regime that has increasingly established an alliance with no longer the Soviets, but the Russians. And, has often shown the middle finger to the Americans.
So, to restate your previous point, "interference" can be good, provided it is done in a calculated manner to not backfire.
