USA is the Nation which spends more money on military than any other Nation. If they can divert that money on diplomatic relations, then nobody can beat USA and They will be Great Again.
Russia and USA must not be treated as rival Nations. They must unite in making Our Planet Earth into a Heaven with their technologies and without killing anybody. Why should Russia and America confine their cooperation to space exploration? There are still many Humans on Earth who cannot afford good food everyday. This is much more serious and important than sending space rovers to Mars. Long live Russia and USA friendship.
