Political commentator Tucker Carlson not only hosted a Nazi apologist on his show but celebrated him as “maybe the best and most honest popular historian in the United States” this week.

Carlson was describing Darryl Cooper, who redefined former British Prime Minister Winston Churchill, one of the heroes of Western civilization without whom Europe would have succumbed to Nazi rule, as the “chief villain” of World War II. Cooper also provided nuggets of laughably false historical non-analysis on social media this week, including the claim that Nazi leader Adolf Hitler made last-ditch efforts for peace with the United Kingdom and “would work with the other powers to reach an acceptable solution to the Jewish problem” but was “ignored.”
