I don't think so... Kruge is using "preservation" as a justification for his actions. But in the very same dialogue shows what his real ambition is. This is just political posturing. The Klingon ambassador was more worried about getting Kirk extradited than the Genesis Device. He doesn't demand any information on Genesis. He doesn't demand any information on the "secret base". They wanted Kirk. I don't think that either exchange proves anything about the general Klingon mindset about outsiders.
