There is extensive critical scholarship that provides illustrations in many areas of scholarship. I've discussed many cases myself, while also citing and often relying on academic studies that disentangle these webs of mystification woven for the general public.

Noam ChomskyMost of us who were opposed to the war, especially in the early '60's - the war we were opposed to was the war on South Vietnam which destroyed South Vietnam's rural society. The South was devastated. But now anyone who opposed this atrocity is regarded as having defended North Vietnam. And that's part of the effort to present the war as if it were a war between South Vietnam and North Vietnam with the United States helping the South. Of course it's fabrication. But it's "official truth" now.
