Yeah, Peace, it's exactly what I would do if I were the Russians, and here's why:

Starting in the 1980's the USA gathered today the most extreme Islamic fundamentalist fighters it could find and armed and trained them and spirited them into Afghanistan to kill Russians. The long range plan was to use radical Islamic fundamentalism to humiliate the Russians, bleed them in an unwinnable war in Afghanistan, and destabilize and break up all the southern republics of the USSR (which mostly contain Islamic peoples) with the hope that it would lead to the breakup of the USSR itself. And it did!

The further part of the longrange plan was for USA and British corporations to move into the oil-rich areas around the Caspian and get the oil (which had been the USSR's up till then). That has also been accomplished.

So the Russians got totally and absolutely screwed between 1980 and now. They lost much of their Soviet federation to separatist movements, and they lost those oil-producing areas as well. They got a society that went from being moderately well-functioning (nothing to write home about...) to being a total, absolute disaster, filled with unemployment, Mafia gangs, poverty, starvation, a very early average death rate, unprecedented levels of crime, violence, and corruption, and a dipsomaniace fool, Yeltsin, in charge of it.

When Putin finally took charge he had to deal with all that, and he is not a drunken fool. The Russians do not have reason to be pleased at all with the USA, which has robbed them blind in the past 15 years, while pretending to do it for the sake of someone's "freedom". (ha! ha!)

They do not wish the USA to continue expanding its sphere of influence further in the Middle East and central Asia, because they've already lost enough.

So of course they are arming Iran to the teeth. Why wouldn't they? It's the latest step in the great game of competing empires.

China, likewise, has quite pressing reasons for arming Iran and seeing that the USA does not take over there...they need the Iranian oil. Look into how the Chinese are assisting Iran. It's another big story.

This is all Realpolitic as usual...struggles over vital resources and spheres of influence, just like it always was. It's never about "freedom", democracy, or other such wonderful sounding concepts. Those concepts are bandied in the media in order to either get our public onside or persuade someone else's public to overthrow their system...so our energy corporations can move in afterward and make a killing.
