In a recent op-ed, The Guardian newspaper has claimed to have “conclusively” proven that British Prime Minister Boris Johnson is just like infamous dictator Adolf Hitler.

The article, which was written by a self-described “expert” on historical parallels, draws comparisons between Johnson’s political tactics and those employed by Hitler during his rise to power in Nazi Germany.

According to the author, Johnson’s use of populist rhetoric, his disdain for the media, and his willingness to stoke nationalist sentiment are all hallmarks of Hitler’s political strategy.

“While we’re not saying that Johnson is a genocidal maniac, there are definitely some troubling similarities between his approach to politics and that of Hitler,” the author wrote.

The article has drawn strong reactions from across the political spectrum, with many accusing The Guardian of irresponsible and inflammatory journalism.

“This is a disgusting and outrageous smear against the Prime Minister and the millions of people who voted for him,” said one conservative commentator. “Comparing Johnson to Hitler is not only offensive, it’s also deeply ignorant of history and the atrocities committed by the Nazi regime.”

Others have pointed out the absurdity of the comparison, noting that Johnson and Hitler have very little in common beyond their shared status as political leaders.

“The fact that anyone would even think to draw a comparison between Johnson and Hitler shows how disconnected from reality some people have become,” said one critic. “It’s a shame that a once-respected newspaper like The Guardian has stooped to this level of sensationalism.”

Despite the backlash, The Guardian has stood by its article, arguing that it is important to call out the “dangerous rhetoric” being used by Johnson and other right-wing leaders around the world.

“Whether or not people agree with our comparison, it is clear that Johnson’s political tactics are deeply troubling and should be called out for what they are,” the newspaper said in a statement. “We stand by our reporting and will continue to hold those in power accountable for their actions.”
