Should the United States maintain a pax americana, or should it not?

应不应该维和平？

Over the course of the semester, we have watched the Romans guarantee peace throughout the Mediterranean world through their pax romana.

这学期的课上，我们已经看罗马人在中世纪保证在地中海地区维罗马帝下的和平。

For the first time in fifteen hundred years a true Roman pax was in sight, and would, if it succeeded, owe its virtues to him.

一千五百年来，真正的罗马人第一次出现在眼前，如果成功，将把它的德归功于他。
