Ruskies are incapable of inventing anything
If you really insist on being a retard...
due to racial limitations
... then at least don't be a racist retard on top of that.
How many countries operate nuclear ice-breakers? Or how many countries provide space taxi services for Americans, when they aren't able to transport their crews themselves?
The first space station was Russian (that implies they didn't copy it from anyone else, doesn't it?). Russian rocket engines were so efficient and reliable that the U.S. bought and used them for Atlas V rockets for decades; Russian floating nuclear power plant (Akademik Lomonosov) is the world's
first operational one, deployed in the Arctic. They have fast breeder reactors in operation (BN-600, BN-800). What else? Buran space shuttle with fully automated orbital flight and landing on its maiden voyage is
something NASA never achieved. Many Nobel Prizes, including the discovery of superconductivity in certain compounds, excellent results - almost the best in the world - in international Mathematics and Physics olympiads. I could go on but it's ultimately pointless, because - as Mark Twain once said - "no amount of evidence will ever persuade an idiot" (how true!).
