I think the issue is that future informants, such as this Chinese guy, are going to simply assume that anything they say to anyone in the USA is potentially going to get leaked. Therefore intelligence will dry up, making the US weaker. I suspect both Wikileaks and most of those doing the leaking are of the opinion that a crippled US intelligence force, and corresponding limitation of the USA operating in the international sphere, is net net a good thing.
