It was both necessary and desirable for us to be so strong at sea that no Sea Power could attack us without risk, so that we might be free to protect our oversea interests, independently of the influence and the choice of other Sea Powers.
我们在海上如此强大是必要的，也是可取的，没有一个海上强国可以不冒风险地攻击我们，这样我们就可以自由地保护我们的海外利益，不受其他海上强国的影响和选择。
