Terrorists hope to create a climate of fear and insecurity that will provoke us to harm ourselves by undercutting the quality of our own liberal democracy. Preventing new terrorist attacks while understanding and avoiding the mistakes of the past will be essential if we are to preserve and support liberal democracy both at home and abroad.
恐怖分子希望创造一种恐惧和不安全的氛围来挑动我们通过降低我们自身自由民主的质量来伤害自己。如果我们要保全和支持国内外的自由民主，那么在防范新的恐怖袭击的同时了解和避免过去所犯的错误就至关重要。这就是奥巴马政府在当下的美国引导的一场辩论。
