Even this modest aim will prove costly, because the Islamic State is also becoming stronger. And it could prove expensive to Russia itself: it is only a matter of time before suicide bombings (such as the recent attack in Ankara) occur in Moscow.
即使这一平庸的目标也将改价高昂，因为伊斯兰国也在日益变强。并且这对于俄罗斯本身来说也可能十分昂贵：莫斯科发生（类似于最近的安卡拉的）自杀式炸弹袭击只是时间问题。
