Funny, I read this in print this morning, then found it on the web from a different source, but I keyed on the same quote you did. Couldn't fit it in the tag line, FR needs to expand that.
I have always wondered if the VC understood how they were used during Tet.
Who knows, for those who survived, it didn't matter, they were finished. But Uncle Ho knew how to snatch victory from defeat, on the backs of those he was "liberating", and with a little help from his foreign "friends". A familiar theme.
I'd like to include Bill Moyers to that lamentable description.
