It is very rare for such negotiations to provide a benefit to terrorist groups. Many states, such as the UK and USA, are unwilling to provide ransom payments so where they are provided they are often privately raised thus cannot be considered to be a result of negotiation. In such circumstances the state will have secured the release of hostages and the life of a state's citizens should be placed above comparatively small amounts of money. Where prisoners are being released as a confidence building measure the terrorists will usually be making some concession as well such as giving up some arms so the state does not end up worse off but there is more trust to enable negotiations to prevent more violence.
