This is not to say that terrible acts of Islamist terror could not happen in the US, or elsewhere. They have, and there probably will be more of them, so long as the Middle East remains in turmoil and revolutionary Islam appeals to disaffected Western youth.
这并不是说美国或其他地区不可能发生伊斯兰恐怖袭击。这种袭击早已发生过，并且未来也许还会更多，如果中东继续动荡、伊斯兰革命继续吸引心怀不满的西方青年的话。但这绝非生存威胁。
