So astronauts work together and athletes compete against one another. What does that have to do with trust? Does that automatically make Russia our friend and all the nations of all the athletes' countries trustworthy? If so we have nothing to fear from nuclear arsenal buildups. No one will ever use them, right ? We have nothing to fear. That's a relief. I can stop worrying about nuclear missiles and chemical/biological warfare and hacking because astronauts/athletes get together in specific circumstances and don't kill one another. :(
