过去总是紧张的,未来是完美的。
The great powers are always searching for opportunities to gain power at the expense of their rivals, and they will use force if they believe it will bring them strategic advantage.
死者既已安葬,活着的人就不要长久地哭泣,而应该尽快做事,每个人都做自己能做的事,并用来使大家互利。 
"We have to be willing to fail, to be wrong, to start over with lessons learned."
