The fallout of these disclosures potentially contributed to a building coup attempt in Turkey by forces loyal to the US (which the US tacitly supported) that burst just a week after the disclosures.
Wikileaks does not only publish "against" America. When it does, it's closer to home for the Americans and we hear more news coverage about it. In any case, wouldn't it okay that there are outlets that produce true news focused on negative aspects of the United States, keeping it accountable? That seems like a positive thing to me - though I don't think Wikileaks is "it".
