The real issue is a total lack of trust on both sides. The Houthis said that their principal condition for attending the talks was the safe passage of 50 wounded Houthis to Oman for medical treatment. On my visit to Saudi Arabia, it was publicly confirmed that that will happen. I hope they understand that their principal condition has been met; it is important now that they do not add new conditions. Likewise, the Saudis need to recognise that the missiles have stopped coming into Saudi Arabia, and they must not add new conditions at this stage. Then people need to sit down and talk.
