For example, only Americans now in their 70s or older today can remember the experience of living through a great depression, the experience of living through a world war, and agonizing whether or not dropping atomic bombs would be more horrible than the likely consequences of not dropping atomic bombs.
例如，只有70多岁或更老的美国人 今天会记得 在大萧条中存活的经验， 在世界大战中存活的经验， 和烦恼到底是 扔原子炸弹的后果比较严重 还是不扔原子弹可能出现的后果比较严重。
