President Biden has rebuffed appeals from G7 leaders to stay in Kabul, the Afghan capital, long enough to get refugees out of the newly conquered country. His answer: “The sooner we can finish the better.” He said that “each day brings added risk to our troops” and warned of the growing threat of an attack from ISIS-K — ISIS in Afghanistan — on the Kabul airport. All of this is what has the world deeply concerned for further suppression of personal freedoms, the abuse of women and the creation of a simmering new centre for terrorist plotting. Will coming months see horrors even worse than those of 9-11? It isn’t silly to worry about another convulsion of young men on a mission to kill for God.
