What We're Following This Morning

Last night’s Republican debate: Yoni described the U.S. presidential debate this way: Ted Cruz, John Kasich, and Marco Rubio offered specifics, while Donald Trump, the front-runner, served up vague generalities. “The trouble for the Republican Party may be that many of the specifics these candidates offered are at odds with the views of the public at large,” Yoni wrote, “while many of Trump’s generalities spoke directly to popular anxieties and frustrations.”

The fifth anniversary of the Japanese tsunami: At 14:46 p.m. Tokyo time (12:46 a.m. ET), people across Japan bowed their heads as a mark of respect for the victims. They were joined by Emperor Akihito and Shinzo Abe, the prime minister. The earthquake and tsunami left more than 18,000 dead or missing.

The death of a Putin aide: Mikhail Lesin died last year at a hotel in Washington, D.C. His family said 57-year-old former press minister had had a heart attack. But the District’s  Medical Examiner issued a report yesterday that said Lesin had, in fact, died of a blow to the head. He also had blunt-force injuries to the neck, torso, arms, and legs, the examiner said.
