MAD is still the deterrent ...
If you look at the actual planes that fly the russian pilots they are either flying early versions of the su27 flanker or mig 29. The russian air force has a budget that represent tidbits of what was the budget in the USSR era.
Yes, but they are decent quality export planes.
At least a heck of a lot better than the F-5 or F-20 we typically offer "third world nations," although the F-15 and F-16 do still get orders from our allies (as will the F-35 shortly).
USA and UK have a bunch of trident IID5 missile so I wouldn't worry much

Yes, MAD (mutually assured destruction) is
still the deterrent!
Despite the insistence of most Americans (largely because of our media) to ignorantly assume we're still at the "initiative" stage of missile defense, and we're trying to build a full, Russian-defending "shield," TMD/NMD is about defending "one-off" attacks.
I mean, how would you like to be Israel or Jordan and the Iranians nuke the US, so we have to respond in kind?
Or North Korea decides to nuke the US, how would you feel as a South Korean citizen to see the US drop a hydrogen bomb in response?
Or what about if Iran or North Korea made an attack on our allies for that matter?
It would be much, much better if the US had a system that would and count intercept that strategic device and ensure
no nukes actually airburst.
Most third world countries hate the idea because it means they have
no deterrence against the US.
But the Russians? They have nothing to fear but MAD, just like us.
Aside from the Topol M
http://en.wikipedia.org/wiki/Topol_M, Russia has develeopped a submarine launched missile version of the Topol M, the Bulava aka ss-nx-30
http://en.wikipedia.org/wiki/SS-NX-30 which is lighter and said to be more accurate.
Yes, and that's about it.
It has decoys and other things, but that too isn't really much in the way of today's TMD/NMD sensory systems.
I don't think that Russia has a real knowledge of how to make stealth missiles or planes.
Actually, the fundamentals of Radar Cross Section (RCS) are
not very difficult to understand.
It's only classified "Secret" level in the US military, largely because the concepts
infiltrate so many aspects of "necessary/common knowledge" in design.
So the Russians very much
do understand RCS and "stealth."
But secondly,
stealth his UTTERLY USELESS on a supersonic traveling vehicle. 
The supersonic shockwaves give the
exact position of the vehicle as it's traveling through the atmosphere, even well beyond the stratosphere.
Only in space would there be the limited 5 minutes or so it could be halfway effective, although the sheer speed the object is traveling still gives it off.
There are doppler effect and other considerations in sensory tracking, even without atmosphere.
In fact, as any scientist or engineer can tell you, some of those very basic principles is how we can tell the difference between a real, re-entry vehicle and something like -- say -- a very light'n bright mylar balloon of larger size.
The su 37 is indeed a great plane but it can't beat a f15 with an aesa apg63v3 radar and thurts vectoring engines. I am not talking about the f22 which owns every russian sukhoi. Even the mig 29 which was said to be better than the f16 was killed in significant numbers in the first gulf war and in kosovo due to piss poor and outdated avionics.
As well as tactics.
Indeed, the US "owned" the Russians and Chinese pilots even back in Korea and Vietnam, despite even "inferior" planes for the situations.
Add in the US' current command'n control capability, and it's all over before it even starts.
Most of sukhoi 27s that were sold recently were sold to many countries that were customers of sukhoi during the USSR period. I am not astonished of this. Putin wants to recreate the cold war era.
Russia has gone into an "unrestricted export" mode, which is rather sad.
They know they can "get away with it" because they are no longer the lesser of two evils.
Hell, I know they are over there saying, "Ha! It's great to see the same level of constant scrutiny and rhetoric being flung at the US for once, what we had to deal with for 50 years!"
I mean, yes, the USSR was the "evil empire" but during the Cold War, we were
never held up to the level of scrutiny they were -- and they were often blamed for things that they didn't even do, or was not their fault.
Now it's the
exact opposite, with people going out of their way to blame the US for anything.
So the Russians can do what they want, kinda like the US during the Cold War (although I would like to think we actually took some care, if not always, of where we sold a lot of our weapons -- even if we didn't bend our own rules regularly).
