The international coalition against the Islamic State group appears to be gaining momentum. On Monday, Paris hosted a conference of around 30 countries and organisations, during which Iraq received pledges of military support as well as other kinds of assistance. But will this make much difference to the overall response to the jihadists?
Nick Witney, a senior policy fellow at the European Council on Foreign Relations, is our guest. He is a former chief executive of the European Defence Agency and a former British diplomat who served in Lebanon, Jordan, and Iraq. He tells us how he thinks the international coalition should deal with the Islamic State militants' rise in Iraq.
