The week's news at a glance.
Chinese and South Korean hackers have been attacking Japanese Web sites, in another sign of growing anti-Japanese sentiment. Last month, demonstrators in China and South Korea protested against a Japanese textbook that they said glossed over Japanese atrocities in World War II. Since then, hack attacks have taken down the Web sites of Japans police and army, as well as the defense and foreign ministries. They are not toying around, cybersecurity expert Itsuro Nishimoto told The Washington Post. These attacks have given us a taste of what role computer systems might play in a real war, in Japan or anywhere.
