Deudney's perspective is that the "space age" race toward developing these technologies has mainly resulted in multiplying risks for the survival of humanity itself, from hypersonic missiles being seen as space weapons, to competition for control and influence far beyond our atmosphere.

"Space is an inherently violent environment," Deudney argues in his conversation with Robert Amsterdam. We are occupying a miraculous oasis of life, an enormously unique and special place, surrounded by trillions of miles of desolate and inhospitable vacuum. In terms of the complex geopolitical questions, our society is very ill-prepared for the conflicts that will be associated with space activity.
