The Brits can show a bit of leadership by flattening a significant area and giving word that the reactions will become more severe.
Why does gubmint (makes no difference what country “work urgently” after the poor man was murdered? Seems its too late for David Haines. The ISIS murderers are indeed rabid mad dog animals and need to be eliminated, that includes their WOMEN and CHILDREN who are being taught to follow in their footsteps. In war there is collateral damage and deaths of innocents but in this case, it is necessary to prevent this “cancer” from growing even further. The U.S has the technology to flatten the entire region but unfortunately, not the WILL to do it.
