For nearly two decades, North Korea has regularly scared the world with its determination to become a fully fledged nuclear weapons state. On Tuesday it took another decisive step on that road. It conducted its third underground nuclear test, this time with substantial explosive power. It claimed to have successfully miniaturised the device that was used, a key step towards fixing a warhead to a ballistic missile. Once again, North Korea took a bow as the only country in the world that is conducting nuclear tests in the 21st century.
近20年來,北韓要成爲核武大國的決心一再讓世界害怕。本週二該國在這條道路上又邁出了決定性的一步。它進行了第三次地下核試驗,這一次具有相當可觀的爆炸威力。北韓聲稱,已成功實現了核武裝置微型化,這是實現彈道飛彈攜帶核彈頭的關鍵一步。作爲21世紀唯一進行核試驗的國家,北韓再一次叫板世界。
