CNN News: 朝鲜频挑衅 美方会否先发制人

朝鲜目前正在进行导弹测试。

A barrage of about a dozen missiles test-fired by Kim just this year and now, his regime in an announcement brags that Kim is preparing to send, quote, bigger gift package to the Yankees.

今年包括现在，金正恩已接二连三发射了十几枚导弹，其政府在一份声明中吹嘘，金正恩打算送“一份更大的礼包给美国佬”。

Senator John McCain tells an Australian broadcaster he`s not confident in America`s missile defense systems to counter the North Korean threat.

参议员约翰·麦凯恩对澳大利亚一家广播公司说，他对美国的导弹防御系统能否应对朝鲜的威胁表示没有信心。

I don`t think that it`s acceptable for the United States of America to have an intercontinental ballistic missile or a missile aimed at Australia with a nuclear weapon on it and depend on our ability to counter it with an anti-missile capability.

我无法接受美国拥有一颗洲际弹道导弹或一颗瞄准澳大利亚的导弹，上面还携带有核武器，并且还要依靠我们的反导弹能力来对付它。

A key question now: what are the alternatives to this flawed missile interceptors?

现在的关键问题是：我们有何备选方案可替代尚有缺陷的导弹拦截器?

In addition to missile defense, you have so-called left-of-launch cyber capabilities that are designed to hack North Korea`s rocket systems.

除了导弹防御，还有专门设计的所谓的“主动抑制发射”网络功能来攻击朝鲜的火箭系统。

You also have preemption, the possibility of a preemptive attack on North Korean missile launch pads or on their missiles themselves.

你也可以先发制人，对朝鲜导弹发射台或导弹本身进行先发制人的攻击。

Analysts say that is the most risky option, that it could provoke Kim Jong-un to turn his guns on Seoul, or on the roughly 28,000 American troops in South Korea. Experts say the U.S. might launch a preemptive military strike on North Korea only if it became convinced that Kim Jong-un was about to fire a missile as an act of war and not just test one.

分析人士称，这是最危险的选择，它可能会激怒金正恩，使他把枪口对准首尔，或是对准在韩国的约2.8万名美国军人。专家表示，美国可能会对朝鲜发动先发制人的军事打击，前提是美国十分确信金正恩将发射一枚导弹进行宣战，而非仅是进行测试。
