Civilisations are not murdered, said the historian Arnold Toynbee. They die from suicide. Though military clout and geographic fortune will sustain America, its republic is flirting with Toynbee’s script. No external threat or domestic cost benefit appraisal would lead a Martian to believe Earth’s greatest power should be in meltdown by its own hand. Whether in China or Canada, or indeed the US, human observers are in disbelief. The speed of America’s turn on itself is historic.
英國歷史學家阿諾德•湯因比(Arnold Toynbee)曾說,文明一般不是被謀殺的,而是死於自殺。儘管軍事實力和地理優勢將繼續支撐美國,但其共和制正在向湯因比的劇本靠攏。沒有任何外部威脅或國內成本效益評估能說服一個火星人相信:地球上的頭號強國竟然會被自己葬送。從中國、加拿大,到美國本身的人類觀察家也都覺得匪夷所思。美國跟自己過不去的速度是歷史性的。
