The Peter principle holds that people in a hierarchy are promoted for doing well in their current role, until they reach a job where they are no longer competent. Skill in one job does not automatically carry over to another, so the best salesperson may become a poor manager and stay there. Laurence Peter and Raymond Hull set out the idea in their 1969 book, which was written as satire but was taken seriously because it described real organisations. Since then it has become a standard way to explain why many managers seem out of their depth.

Israeli reports also say the cabinet directed the military to prepare for a possible new attack on Iran.

Angkor, near Siem Reap in northern Cambodia, was the capital of the Khmer Empire, which ruled much of mainland Southeast Asia between roughly the 9th and 15th centuries. At its height the city spread across about 3,000 square kilometres, making it the largest pre-industrial city on Earth by area. Its growth depended on water: huge reservoirs called barays, along with canals and embankments, stored monsoon rain and carried it to rice fields. That system let farmers harvest more than once a year and fed a very large population through the dry season. The temple complex of Angkor Wat, built in the early 12th century, is the best-known monument and still stands at the heart of the park.
