HAVANA – Fidel Castro is showcasing a theory long popular both among the far left and far right: that the shadowy Bilderberg Group has become a kind of global government, controlling not only international politics and economics, but even culture.

The 84-year-old former Cuban president published an article Wednesday that used three of the only eight pages in the Communist Party newspaper Granma to quote — largely verbatim — from a 2006 book by Lithuanian-born writer Daniel Estulin.

Estulin's work, "The Secrets of the Bilderberg Club," argues that the international group largely runs the world. It has held a secretive annual forum of prominent politicians, thinkers and businessmen since it was founded in 1954 at the Bilderberg Hotel in Holland.
