A court in Turkey has ordered YouTube to be switched off. Why? Why do governments always ban Google's video-sharing behemoth? Videos insulting politicians.

And it's not Turkey's first time around this hoary old block. On one previous occasion, Turkey blocked YouTube after clips were found insulting the nation's founding father, Mustafa Kemal Ataturk, more commonly known simply as 'Ataturk'.

It is against the law to insult Ataturk, a career soldier who repelled Churchill's forces at Gallipoli in the First World War (almost single-handedly), and then went on to lead the Turkish nationalist movement, which created the country from the ashes of the Ottoman empire. He then dragged Turkey into the modern world with a reforming, pragmatic but steady hand. And he had a FANTASTIC moustache. (I could go on. He's something of a hero.)

A court in Sivas ordered the block on YouTube, after complaints about a video on the site that insults Ataturk, President Abdullah Gul, Prime Minister Recep Tayyip Erdogan and the Turkish army.

The latter may be the crucial point here. Sitting as it does on the faultline between east and west, Turkey is periodically stretched between western academics and Islamic reformers. Traditionally the Army has been the slightly less than benign father figure to these squabbling kids. As a consequence, the military is pretty powerful in Turkey. Powerful enough to prevent Turkish youth from watching the Samanda Barbie Girl video.
