Consider the absence of an early tsunami warning system in the worst affected countries. It is easy to blame people for lack of foresight, but none of the nine hardest hit countries had developed one.
想一想在那些受灾最重地区竟然没有先期海啸预警系统，你很容易责备那里的人们目光短浅。但是九个受灾最重国家无一拥有此系统，他们不可能都如此冒失吧！关键问题不在个人之错。这种疏忽源于缺少适当的、且能预警各种潜在灾难的国际机制。
