“Prime Minister Hun Sen of Cambodia has been in power for more than 30 years. On Wednesday, he vowed to stay in power. “After witnessing the treasonous acts of some Cambodians in recent days,” he said, “I have decided to continue my job for another 10 years.” Citizens might have thought it was up to them to decide, in general elections next year, who will govern their country. Mr. Hun Sen has set them straight: He has no intention of losing that election or future ones to an opposition that did better than expected in the last vote in 2013. If this means charging opposition leaders with treason, so be it.”
