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.
Obama doesn't have the ability to calulate this IMO. Someone is playing him as well, though he imagines it's his wit. He's really not that important on the International Stage now..apart from how much more they can milk out of country in revenues , and the Muslim nations are part of the deals he has struck as we know.
Russia and China have been cuddling up close behind the scenes for sometime. Neither give a rats dung about the middle-easterns, they each have an ultimate goal which is the resources in the middle east... and that's a silent war between them which will play out in the future.
Interesting they both see Iran's issues with Israel as standing in the way. Thus they have to let the Irianian leadership in as a player on their team.
I suspect Russia will one day join with Iran and go after Israel...Russia can't do it alone, history has shown thus, so taking them on as an alley, and ditching them once they have their armorment located throughout the middle-east, and in place. China will be mostly a spectater while positioning themselves to come into the fray once Russia turns on the Iranians. China's not about to let Russia take the resources without a fight if they have to, but by then Russia will be weakened....they'l come swarming in.
Course this is just speculating...but fun to watch the players. I have often said if you want to know what's happening just watch who is sleeping with who in all nations leadership.
But the US will at most be called on for their military and money...if that, and by then the American people will likely be fed up with war and let the best man win. Libya is a good example.
