Gideon Rachman's blog: Somebody seems to have forgotten to tell the Turkish parliament that it is traditional to greet speeches by Barack Obama with regular standing ovations and whoops of approval. It was rather strange and unsettling to listen to an Obama speech on Monday that was not interrupted in this way. It forced you actually to listen to what he was saying.

Of course, there were a few rounds of applause punctuating the speech. Obama got clapped for using a Turkish word, for mentioning some successful Turkish basketball players, for condemning the PKK as terrorists and for asserting that "the US is not and never will be at war with Islam".
