You clearly intentionally picked something it would be hard to determine the original material source facts came from.
A news report for 1968? I'm supposed to source, defend that?
Cronkite called the tet offensive a massive failure by the US military. It wasn't. Cronkite gave victory to the North, in a propaganda victory.
It was a huge military defeat, heavy losses for the north, but thanks to Walter, a political victory.

Or, do you think NPR lies?
