I didn't mean tomorrow ("if we ever.."), or the day after. I meant one day when the US and Russia get along as well as China and the US do. It's not like we'll be at not-war war long into the future. Building the bridges and tunnels would take probably a decade or two, the way we build things. But if we did, then much of China's trade that goes over airfreight could come over via rail... one day.
