But sometimes the line really is crossed, all relevant players know it, and the consequences are potentially profound. The United States’ failure so far to cut off its military aid to Egypt in response to the regime’s massacre of hundreds of Muslim Brotherhood supporters, in the streets and in prisons, is as clear a recent case as one can find.
但有时这条线真的会被越过，所有相关方都知道这一点，而且后果可能影响深远。美国至今没有因为军队在街头和监狱中屠杀数百名穆斯林兄弟会支持者而砍掉其对埃及的军事援助，这是人人都看到的最新例子。
