Better to overreact than under react - Here’s Jeff Jacoby in “Failures of intelligence”: “If intelligence failures are inevitable — and in a world of human fallibility, they are — we are better off worrying too much about our enemies and taking steps to defeat them than worrying too little and being caught, unready, when they attack. Worrying too much led the United States and Britain to topple a brutal tyrant. Worrying too little led to 9/11 and 7/7.”
