两个欺软怕硬，恃强凌弱的东西

911反恐是迄今为止北约自动防卫协议唯一开启的一次（the first and the only one so far). 美国是被援助国，Troops from NATO allies Denmark, the UK, Canada, Germany, France, Italy, the Netherlands, Turkey, Spain etc., and non-NATO members Australia, New Zealand, Ukraine, Estonia, Lithuania, Latvia, Finland and many others joined the fight in Afghanistan.

1,000多个来自这些国家的士兵战死在那里。如果川普政府所叫嚣的武力征服格陵兰真去实现，将是北约第五号自动防卫协议第二次开启，美国这次将是和普京俄国一样的侵略国。
