While it had been obvious and well known that Russia & China were aiding the N. Vietnamese against us in that war, the Son Tay Raid was the first time we got absolute evidence of their involvement (Green Berets killed a bunch of "advisors" who were in the NVA camp).

That "the adults" today can't seem to understand that we're in the same mess - but this time being lured into greater conflict with RUS/China/Iran is a testament to how mediocre & short sighted the people in charge really are.
