I am truly sorry to say it, but UNESCO really is an appalling organisation. Good article here by Liberal Vision.

The links to Global Witness are well worth following up, too. I have a lot of time for Global Witness.
UNESCO have put millions of UN money into “reconstruction” of Tamerlane monumental architecture in Uzbekistan. Astonishingly, the process often involves demolition of the original remains being “reconstructed”. The entire purpose of these Disneyland reconstructions is to host Karimov regime spectaculars featuring singing soldiers and massed ranks of dancers celebrating the cotton harvest.
UNESCO seems devoid of moral sense – indeed any sense. I remember, as an internationalist, being appalled when Thatcher withdrew Britain from UNESCO for a while. But she was right.
