I think a few forget the differances between the NVA, Viet Cong, and the Taliban. Then consider the support each received, and from where.
Then, as previously pointed out, the Tet Offensive was a huge tactical loss, bordering on disaster militarily for the Viet Cong. It was only because of the US press that it became a political victory.
That's a lesson forgotten, or purposely ignored by organizations like the New York Times.
Personally I take delight in reading of the NYT financial problems. I strongly hope they fold up.
