今日はちょっとお堅い政治？ と言うより、USA のSecurityのお話です。
NSA official Rob Joyce told guests at a Wall Street Journal security conference that hacking-related Chinese activity had been climbing in recent months. He was concerned the country was "prepositioning" itself to attack "critical infrastructure" such as energy, health care, finance and transportation. China's hacking as of late has revolved around spying and swiping trade secrets, so this would be out of the norm.
It's not certain exactly what would prompt an escalation, although there are multiple possible factors. China and the US have been engaged in a trade war in recent months. And while it happened too recently to play into Joyce's remarks, the arrest of Huawei's CFO hasn't exactly helped diplomatic relations.
