you must also remember that subspace drive makes it possible to cross the fs universe in a mater of days. they are not like star trek where they must criuse for days or weeks to get from one place to anther. therefore fresspace ships need only a short criuse duration. sience vessels poribly have the longest duration upwards to a year, to scout for new supspace nodes.
as for nukes they are quite damaging, the reason we dont have fusion reactors is because they have a tendency to vaporize any kind of fuel feed system and therefore prevent a continueous maintainable reaction. nukes can vaporize metal, atmosphere or not. and though a nuclear shockwave can blast through houses and concrete bunkers, it is still merely a side effect of the blast. the heat alone would leave a mile wide crater in any block of any metal or composite. one thing few people know about h-bombs, is the yeild is proportinal to the amount of deutrium surrounding the initiating nuke.tritium is a control that actually limits the size and radiation output of the blast. more deutrium, more boomb!
now vasudans might like to own aquariums, but i very much doubt fish as being their primary diet. seeing as vasuda was a desert, (at least before it was rendered a smoldering ruin by the lucifer). they probibly eat snakes, bugs, and stuff.
