Here’s an excellent piece by Jonathan Tobin on William F. Buckley’s extraordinary effort to expel antisemites like Pat Buchanan and Joseph Sobran from The National Review and the conservative movement: Bill Buckley and the Jews.

Buckley would himself acknowledge that prejudice was a presence in his own home growing up. And as a youngster, Buckley admitted that he was a fan of Charles Lindbergh and his “America First” movement, whose flirtation with anti-Semitism was of a piece with its advocacy of appeasement of Adolf Hitler’s Nazi Germany.

But as National Review took flight in the late 1950s, anti-Semitic writers found themselves on the outside looking in. So, too, did apologists for the extremist John Birch Society.

But despite the fact that his conservatism was one that was informed by his own Catholic faith (something that was consistently made clear in the pages of National Review), Buckley made his journal, and by extension, the movement for which it served as an unofficial bible, off-limits to the anti-Semitism that was commonplace in the world in which he grew up.

Though he didn’t always agree with all of its policies, Buckley was also a consistent supporter of Israel. A staunch anti-Communist, he was also deeply supportive of the movement to free Soviet Jewry at a time when many in this country (including some Jews) were loath to speak out because it might be interpreted as opposition to a policy of detente with Moscow.

Long after he chased the Birchers out of NR, Buckley found himself forced to confront the issue again. When longtime colleagues Pat Buchanan and Joseph Sobran used their bully pulpits on the right to bash Israel and stigmatize Jews for their support for the state, it was again Buckley who took on the haters.

Buckley repudiated Sobran’s writing, which he labeled anti-Semitic, and pushed him off the magazine’s masthead.

As the issue continued to percolate in the aftermath of the Persian Gulf war in December 1991, he devoted an entire issue of the magazine to an essay titled “In Search of Anti-Semitism” (which was also the title of the book he later published on the same subject), in which he took on Buchanan, who was preparing an insurgent run for the White House against the first President Bush.

His conclusion was damning: “I find it impossible to defend Pat Buchanan against the charge that what he did and said during the period under examination amounted to anti-Semitism, whatever it was that drove him to say and do it,” Buckley wrote.
