I think the old b'stards like me and D-Man having grown up around this, have a very different opinion on this situation.
Now, when the front page of your newspapers, are a Russian convey, carrying a missile the size of Birmingham's BT Tower - then worry.
China and Russia make their rubles and renminbi from the West, via natural resources and cheap labour/products. Whilst trying to maintain a rather communist attitude to varying degrees, they don't mind of few of our pounds! How many of those do you reckon come from North Korea?
So, if some neighbours up the road buy tons of crap from me all year, and someone who used to be a mate, starts behaving like an utter moron up the road - and doesn't help me out in any way shape or form, who am I going to now side with?
Russia and China are trying to avoid wars, not create them. That's why they are so against hostile USA actions, because that causes problems. They threatened all sorts about Iraq, as they didn't want the region destabilised.
I am not a fan of Putin, but I have heard speeches of his at UN gatherings, where he tears the USA a new one for creating problems not solving them with diplomacy.
(Of course, there is a thought that they would not want the USA having too much power in another region full of natural resources)
Also, even in mainstream USA media, there was a big conference at the Washington Press Club (well, there have been multiple) by ex-military generals et al, speaking of strange things disengaging entire nuclear weapons bunkers... Russia have had similar things, as I believe allegedly have China.
Fox news reported it too:

Crazy as it sounds, this has been reported multiple times, and is recorded in FOI documentation...
Don't believe Fox News? Maybe you would care to watch the entire thing streamed LIVE by CNN?
Disclosure Conference, National Press Club 27 Sept 2010
These are some of the world's top level military nuclear personnel. I've never been sure if this makes me more or less nervous to be honest, but I'm sure as heck not ignorant enough to dismiss their claims.
