POV statement which couldn't be salvaged 

I removed the following statement from the article, hoping that someone will rewrite this.
"Former CIA agent John Stockwell, who was stationed in Angola while working with the CIA, argued that the CIA murdered 10,000 Angolans by arbitrarily warmongering.http://www.informationclearinghouse.info/article4068.htmhttp://www.youtube.com/watch?v=c35COXObeo8"

Reasons I think it's POV:
"arbitrarily" - Please elaborate, and explain how this is relevant to the article
"warmongering" - I think this term is rarely appropriate in an encyclopedia, and certainly not here.  There are many other better words.
The 10,000 figure isn't even mentioned in the article itself.  So, if it's not important or noteworthy enough to put there, why does it belong in a broad article about the country?
The 10,000 figure appears to come from his recollection.  Since when do we rely one person, an activist at that, to be the sole source for a casualty estimate?
The U.S.'s involvement is more of a side note here, and does not really fit in with the rest of the description of Angola's history.  In another article about, I don't know, CIA activities in Angola, maybe, but not here.
