North Korea has long been adept at flaunting its willingness to take risks, provoking a crisis in 2010 by sinking a South Korean naval vessel and shelling a South Korean island. This spring, it conducted a nuclear test and a series of missile tests, accompanied by a stream of bellicose rhetoric.
很久以来，朝鲜一直熟于展现其冒险的意愿，2010年，朝鲜击沉一艘韩国军舰并炮击韩国岛屿，引发了一场危机。今年春天，它又进行了一次核试验和数次导弹试验，并数次发表战争宣言。
