Buckley is wrong here, but that takes away nothing from his illustrious career. He was, after all, one who in 1955 stood athwart history and yelled "Stop." He inspired others who have since taken up the mantle. I grew up politically on National Review during the 80's (favorite reading material of one Ronald Reagan) and I'll always feel a debt of gratitude to this man.
Just found a bunch of 60's era issues of the "National Review". Articles were incredibly prescient and many are still relevant.
National Review charges to access the online archives, probably just to force the underpriviledged to have to resort to the public library.
