From a New York Times op-ed:
"(A)uthoritarian regimes and armed militants of the Arab world get sympathetic treatment on BBC Arabic. When Saddam Hussein was in power, he was a great favorite of the service, which reported as straight news his re-election to a seven-year term in 2002, when he got 100 percent of the vote. President Bashar al-Assad of Syria enjoys similar favor. When a State Department representative referred to Syria as a dictatorship, his BBC interviewer immediately interrupted and reprimanded him.
"The Arabic Service not only shields Arab leaders from criticism but also tends to avoid topics they might find embarrassing: human rights, the role of military and security forces, corruption, discrimination against minorities, censorship, poverty and unemployment. When, from time to time, such topics do arise, they are usually dealt with in the most general terms: there may, for instance, be guarded references to “certain Arab countries.”
"By contrast, the words and deeds of Western leaders, particularly the American president and the British prime minister, are subject to minute analysis, generally on the assumption that behind them lies a hidden and disreputable agenda. Last summer, when the British arrested two dozen people alleged to have been plotting to blow up airplanes crossing the Atlantic, a BBC presenter centered a discussion on the theory that these arrests had taken place because Tony Blair, embarrassed by opposition to Britain’s role in the conflict between Hezbollah and Israel, wanted to distract the public while at the same time associating Muslims with terrorism."
