Voyage from Yesteryear

As nuclear war looms, a probe has discovered an Earthlike planet waiting with open biosphere; and the Americans launch a crash project to colonize Chiron. Science can't yet transport living humans between stars, but it can send DNA codes to become children who will be raised by humanlike robots. Amazingly, it works. The colonists are everything their home-planet could hope for--except that they really mean it about all that liberty stuff. But now the Earthmen have had their war, survived, rebuilt--and sent ships to Chiron. They're the government. They've come to help. But the colonials have such an attitude. OH NO! HUMANS FROM EARTH! Late in the 21st century nuclear war once again loomed on the horizon. And this time there would be no escape. But an American probe has discovered a second life-bearing planet waiting with open biosphere for refugees from Earth; so that freedom, and the human race itself, shall not perish from the universe, the Americans launch a crash project to colonize Chiron. There's only one problem: the science and engineering of the time are not up to the task of transporting living humans between star systems. The answer: send a "colony" of frozen sperm and ova, and use robots to quicken them at the other end. Then use humanlike robots to raise the resulting children. Amazingly, it works. The children and their children's children are happy, healthy, and steeped in the ideals of America's Founders. They are everything their home-planet sponsors could have hoped for except that they really mean it about all that liberty stuff. But now the Earthmen have had their war, survived, rebuilt and come to Chiron in new fast ships. They're the government. They've come to help. But the damned Colonials have such an attitude. An army from Earth battles to regain control over a space colony that has developed advanced technology but has evolved into a society that will do anything to retain their liberty. Reissue. An army from Earth fights to regain control over a space colony that has developed advanced technology, but has evolved into a lawless society.
