With the historical memory of the country virtually non-existent it's good to know there are a few wise heads still around at the BBC who are, at least, aware of what's going on in the world even if they can't share this knowledge with viewers who pay to keep the BBC going as a public service. Adam Curtis's documentaries are usually very good but he makes only one or two a year. Why on earth he isn't given a weekly late-night history slot escapes me. Time surely for BBC viewers to organise a petition or threaten a licence-fee boycott if the Corporation continues to degenerate. In the meantime read Curtis's blog and learn about Yemen.
