Russia has alway been good
at emergencies. When no money and no lives are spared, results are easy to achieve. The basic science was available for tens of years. And, Russia has never been poor in brains. The problem was not to kill them. The man oficially credited with the beginning of Russian Space Program, Korolev, was extracted from a labor camp and offered an alternative: go back or put a man in space. Worked wonders.

things will never get back to normal, and that they already have.
