Now, it looks as if Kim Jong-un, the North’s 33-year-old leader, has a different plan — one intended to improve his ability to strike the United States without setting off an American military response. Instead of going for distance, he has stepped up the testing of missiles that fly high into space — on Sunday, one reached a height of more than 1,300 miles — and then plunge down through the atmosphere, mimicking the kind of fiery re-entries a nuclear warhead would undergo if fired over a much longer distance. Instead, the payload lands in waters a few hundred miles or so from North Korea’s coast. “They can simulate an ICBM warhead on this kind of trajectory,” David C. Wright, a senior scientist at the Union of Concerned Scientists, a private group in Cambridge, Mass., said in an interview. “It’s a kind of steppingstone.” John Schilling, an aerospace engineer and an expert on North Korea’s missile program, called this relatively low-key experimentation a possible hedge against a military response. Sunday’s unobtrusive test, he said, could nonetheless “represent a substantial advance” that might bring the debut of a working intercontinental missile closer than previously estimated. The best guess of nongovernmental experts puts an ICBM debut at roughly 20... Link to the full article to read more
