Last May the generals intervened to break the dismal cycle,claiming impartiality.They spoke of reconciliation and tried to start discussions with Mr Thaksin. But recently they have changed their minds,perhaps to please the establishment around the court of the old king. Impeaching Yingluck is only part of it. The generals are drawing up a constitution designed to keep populist parties like Mr Thaksin's Pheu Thai from power.They intend to rule for as long as it takes to restore a supposed moral order.
