Guns for Astronauts ?

The astronauts from US and China are using guns for their own protection, that surprising fact contrast with the fact that no enemy exist in space or yes? Here is exactly the point there is enemy in space and they know it, there are afraid that the other use the space as a arm, it seems that nobody want to put arms in space and a hight risk exist of a race in space because of this fear of the other. In that point is where is important the establishing of a new treaty about arms in space and stop the possible race that will not benefit to anybody. The guns are charged by the daemon if exist will be used ( eventually accidentally ) and the results for the international community could be huge. I hope that all the states will take that into consideration and will agree in some text to assure this situation. Full respect. Xavier from ISU city.
