They were spinning the facts then, and have done so since to cover their complicity in the genocide that followed in SE Asia. Had we pressed the advantage after TET, invaded the North, pulled out the stops and won a decisive military victory, millions might have lived. The press was a large part of preventing that, and helped minimize the impact of the ensuing slaughter by not reporting it.
Here we go again, with the only advantage being that now we have those who were duped in the past and who now know better. We know the enemy for what they are.
