Such was the existentialist worldview of US President and Nobel Peace Prize laureate Theodore Roosevelt, a major advocate of American expansionism: “A just war is, in the long run, far better for a man’s soul than the most prosperous peace.” A century later, another American president, Barack Obama, immersed in two hopeless wars in the Middle East, received his Nobel Peace Prize with an apology for “just wars.”
历史告诉我们，外交通常只有在强权的支持下才能带来结果。这就是美国前总统、诺贝尔和平奖获得者西奥多·罗斯福的存在主义世界观。他是美国扩张主义的主要倡导者之一。他曾说：“从长期起来看，正义的战争比最富庶的和平年代更能让人的灵魂受益。”一个世纪后，现任美国总统奥巴马在中东身陷两场无望获胜的战争。他也获得了诺贝尔和平奖。在获奖发言中，他为“正义的战争”带来的伤害道歉。
