The frightful and bloody hours of Friday night and Saturday morning in Munich and Kabul – despite the 3,000 miles that separate the two cities – provided a highly instructive lesson in the semantics of horror and hypocrisy. I despair of that generic old hate-word, “terror”. It long ago became the punctuation mark and signature tune of every facile politician, policeman, journalist and think tank crank in the world. Terror, terror, terror, terror, terror. Or terrorist, terrorist, terrorist, terrorist, terrorist.
