1st Law of Space Warfare

It's been stated as a rule-of-thumb and a pretty good one, that warfare is 90% logistics.  As far as space warfare is concerned, I would posit a law (and by law I mean a total S.W.A.G. unproven theory on my part)  that war in or from orbit is 99% logistics.  Interplanetary warfare would be 99.9% logistics and interstellar warfare would be 99.99% or more logistics.  It could be off by several factors but the main argument is that space warfare would be almost entirely mostly fighting for survival against the environment and not an 'enemy.'  Thus surviving longer than one's enemy is 'winning.'  This theory also has other implications politically concerning space colonization and eventual weaponization.   As the "logistics" part of space warfare would pretty much look exactly like its civilian use-of-space logistics, then space colonization IS space weaponization or close enough to make weaponization inevitable.
