Millions of residents of northern Japan will have felt a sense of deja vu on Tuesday morning when they were alerted to a North Korean missile flying overhead. Five years earlier, they had twice been shaken from their slumber by Japanese government warnings to seek shelter after missile launches by Pyongyang.
The intermediate-range missile involved in this week’s test was far from buzzing the rooftops of Hokkaido farmhouses – it flew at an altitude of 1,000km as it made its way to the Pacific Ocean, where it splashed down, without incident, more than 3,000km east of Japan.
