I hate to break it to you but the Russians are pretty good at building heavy lift boosters and they have shared their technology with us.
But I do find it suspicious that for all of the their vaunted space/space station experience, there's
an awlful lot of sophmoric things wrong with the ISS.
What did we get out of it?
What did any of the other "partners" get out of it?
The Russians are lousy at building orbital hardware; and they don't have a heavy lift booster capable of launching the modules of the ISS.
The RS-68 is touted as multichambered and more powerful than the F-1 from the Saturn V, but is basically four engines welded together and sharing some components. Each bell puts out 1/4 of an F-1. I'm not too sure it's in production per se, but is a recent design and has been used to launch quite a few satellites via a Russian-US company I think.
Where the Russians had a good idea is, incremental improvements to engine design (a capitalist sounding idea, doncha think?) and building lots of any design that turns out reliable. They've built the most efficient kerosene burning engines ever developed. The root of the design is the German V-2. There's a Korolev biography that includes a vintage photo of Korolev standing next to a captured V-2 engine.
