Of course, if there's one thing this new century has taught us, it's that we cannot separate our work here at home from challenges beyond our shores.

当然，如果说新的世纪教会了我们什么的话，那就是，我们不能将国内事务和国外的挑战孤立开来。

My first duty as Commander-in-Chief is to defend the United States of America. In doing so, the question is not whether America leads in the world, but how. When we make rash decisions, reacting to the headlines instead of using our heads; when the first response to a challenge is to send in our military -- then we risk getting drawn into unnecessary conflicts, and neglect the broader strategy we need for a safer, more prosperous world. That's what our enemies want us to do.

作为总司令，我的首要任务是保卫美利坚合众国。这样做，问题不在于美国是否领导世界，而是如何领导。当我们做出轻率的决定，只是对媒体报道作出反应而没有用脑思考时，当我们对于某个挑战的第一回应是出兵时，我们便会冒险卷入不必要冲突，而忽略维护更安全、更繁荣的世界所需要的整体战略。而这正是我们的敌人希望我们做的。

I believe in a smarter kind of American leadership. We lead best when we combine military power with strong diplomacy; when we leverage our power with coalition building; when we don't let our fears blind us to the opportunities that this new century presents. That's exactly what we're doing right now. And around the globe, it is making a difference.

我对智慧型美国领导方式深信不疑。当我们把军事力量和有力的外交结合起来时，当我们利用我们的力量建立同盟时；当我们不被恐惧蒙蔽而能看到新世纪带来的机遇时，我们便能发挥最好的领导作用。我们现在正是这样做的，我们更将其运用到全世界：我们正在改变世界。

First, we stand united with people around the world who have been targeted by terrorists -- from a school in Pakistan to the streets of Paris. We will continue to hunt down terrorists and dismantle their networks, and we reserve the right to act unilaterally, as we have done relentlessly since I took office to take out terrorists who pose a direct threat to us and our allies.

首先，我们与全世界成为恐怖分子袭击目标的人民站在一起——从巴基斯坦的一所学校到巴黎的街头。我们将继续追捕恐怖分子并摧毁他们的网络；我们保留采取单边行动的权利，正如我执政以来所做的那样，我们将坚持不懈地除掉对我们及我们的盟友构成直接威胁的恐怖分子。

At the same time, we've learned some costly lessons over the last 13 years. Instead of Americans patrolling the valleys of Afghanistan, we've trained their security forces, who have now taken the lead, and we've honored our troops' sacrifice by supporting that country's first democratic transition. Instead of sending large ground forces overseas, we're partnering with nations from South Asia to North Africa to deny safe haven to terrorists who threaten America.

与此同时，我们也在过去13年中得到一些教训，并为此付出了高昂的代价。美国军人将不在阿富汗的山谷中进行巡逻，而是训练他们的安全部队。现在主要由阿富汗安全部队负责阿富汗的安全。我们对我国军人在支持阿富汗第一次民主过渡方面所做出的牺牲表示敬意。我们不再向海外大规模派遣地面部队，而是与南亚乃至北非各国合作，让威胁美国的恐怖分子没有栖身之所。

In Iraq and Syria, American leadership -- including our military power -- is stopping ISIL's advance. Instead of getting dragged into another ground war in the Middle East, we are leading a broad coalition, including Arab nations, to degrade and ultimately destroy this terrorist group. We're also supporting a moderate opposition in Syria that can help us in this effort, and assisting people everywhere who stand up to the bankrupt ideology of violent extremism.

在伊拉克和叙利亚，美国的领导作用，包括我们的军事力量，正在阻止着伊斯兰国的扩张。我们没有在中东卷入另一场地面战争，而是统领着一个包括阿拉伯国家在内的广泛联盟，来削弱并最终摧毁这个恐怖组织。我们在叙利亚支持能够帮助我们做到这一点的温和反对派，支持世界各地对抗暴力极端主义这种破产意识形态的人们。

Now, this effort will take time. It will require focus. But we will succeed. And tonight, I call on this Congress to show the world that we are united in this mission by passing a resolution to authorize the use of force against ISIL. We need that authority. (Applause.)

这些努力需要时间，也需要专注，但是我们会成功。今晚，我吁请国会通过决议，批准对伊斯兰国使用武力，以此向全世界展示我们在这一使命中的团结一致。

Second, we're demonstrating the power of American strength and diplomacy. We're upholding the principle that bigger nations can't bully the small -- by opposing Russian aggression, and supporting Ukraine's democracy, and reassuring our NATO allies.

其次，我们将彰显美国的实力与外交。我们秉持大国不能欺凌小国的原则，反对俄罗斯侵略，支持乌克兰民主，并让我们的北约盟国放心。

Last year, as we were doing the hard work of imposing sanctions along with our allies, as we were reinforcing our presence with frontline states, Mr. Putin's aggression it was suggested was a masterful display of strategy and strength. That's what I heard from some folks. Well, today, it is America that stands strong and united with our allies, while Russia is isolated with its economy in tatters. That's how America leads -- not with bluster, but with persistent, steady resolve.

去年，当我们与盟国一起对俄罗斯实施制裁时，一些人说，普京先生的侵略是战略和实力的巧妙展现。可是今天是美国坚定地与盟国团结在一起，而俄罗斯处于孤立，它的经济风雨飘摇。这就是美国领导的方式，不是通过虚声恫吓，而是通过持之以恒、坚定不移的决心。

In Cuba, we are ending a policy that was long past its expiration date. When what you're doing doesn't work for 50 years, it's time to try something new. And our shift in Cuba policy has the potential to end a legacy of mistrust in our hemisphere. It removes a phony excuse for restrictions in Cuba. It stands up for democratic values, and extends the hand of friendship to the Cuban people. And this year, Congress should begin the work of ending the embargo.

在古巴方面，我们结束了早已过时失效的政策。当你做了50年的事不再奏效之日，就是将要改弦更张之时。我们在古巴政策上的转变能够结束两国间的长期不信任，能够消除古巴限制的虚假借口，能够代表民主价值观，能够向古巴人民伸出友谊之手。今年，国会应该开始相关工作，结束贸易禁运。

As His Holiness, Pope Francis, has said, diplomacy is the work of "small steps." These small steps have added up to new hope for the future in Cuba. And after years in prison, we are overjoyed that Alan Gross is back where he belongs. Welcome home, Alan. We're glad you're here.

正如罗马教宗方济各所言，外交是积小步而成的。这些小步累积在一起，就成为了古巴未来新的希望。阿兰·格罗斯在被监禁多年后，回到了属于他的地方，我们为此感到万分欣喜。阿兰，欢迎回家。

Our diplomacy is at work with respect to Iran, where, for the first time in a decade, we've halted the progress of its nuclear program and reduced its stockpile of nuclear material. Between now and this spring, we have a chance to negotiate a comprehensive agreement that prevents a nuclear-armed Iran, secures America and our allies -- including Israel, while avoiding yet another Middle East conflict. There are no guarantees that negotiations will succeed, and I keep all options on the table to prevent a nuclear Iran.

我们与伊朗的外交也取得成效。十多年来第一次，我们使伊朗核计划的进程暂停，使伊朗核材料的储备降低。到今年春天之前，我们有机会就一项全面协议进行谈判，这项协议将防止伊朗拥有核武器，保障美国及其包括以色列在内的盟国的安全，同时还能避免再次发生中东冲突。虽然不能保证谈判能成功，但为防止出现核伊朗，我不排除任何选项。

But new sanctions passed by this Congress, at this moment in time, will all but guarantee that diplomacy fails -- alienating America from its allies; making it harder to maintain sanctions; and ensuring that Iran starts up its nuclear program again. It doesn't make sense. And that's why I will veto any new sanctions bill that threatens to undo this progress. The American people expect us only to go to war as a last resort, and I intend to stay true to that wisdom.

但是国会此时此刻通过的新制裁，几乎就是宣告了外交失败——让美国与盟国疏离，让伊朗重新开始核计划。这没有道理。因此我会否决任何可能抵消这一努力的新制裁议案。美国人民希望我们只在最后才会诉诸于战争，我想实践这一明智的理念。

Third, we're looking beyond the issues that have consumed us in the past to shape the coming century. No foreign nation, no hacker, should be able to shut down our networks, steal our trade secrets, or invade the privacy of American families, especially our kids. So we're making sure our government integrates intelligence to combat cyber threats, just as we have done to combat terrorism.

最后，我们要关注那些在过去困扰我们，并将影响下个世纪的问题。任何外国势力，任何黑客，都不应该能够破坏我们的网络，盗取我们的商业机密，或者侵犯美国家庭的隐私，特别是孩子们的隐私。我们要确保政府会整合一切情报来打击网络威胁，就像我们打击恐怖主义一样。

And tonight, I urge this Congress to finally pass the legislation we need to better meet the evolving threat of cyber attacks, combat identity theft, and protect our children's information. That should be a bipartisan effort.

今晚，我敦促国会通过这项议案，我们需要这项议案来更好地应对与日俱增的网络袭击威胁，抗击身份盗窃，保护孩子们的信息。两党应齐心协力为之努力。

If we don't act, we'll leave our nation and our economy vulnerable. If we do, we can continue to protect the technologies that have unleashed untold opportunities for people around the globe.

如果我们不采取行动，我们的国家和经济将容易遭受破坏。但如果通过这项议案，我们就能继续保护这些能够为全人类释放出无限机会的技术。

In West Africa, our troops, our scientists, our doctors, our nurses, our health care workers are rolling back Ebola -- saving countless lives and stopping the spread of disease. I could not be prouder of them, and I thank this Congress for your bipartisan support of their efforts. But the job is not yet done, and the world needs to use this lesson to build a more effective global effort to prevent the spread of future pandemics, invest in smart development, and eradicate extreme poverty.

在西非，我们的部队、科学家、医生、护士和医护工作者正在对抗埃博拉——挽救无数人的生命并遏制疫情扩散。我为他们感到无比自豪，我也感谢国会两党的支持。但这项工作还没有完成——世界需要从中吸取教训，从而得以在全球范围更有效地防止未来流行病的蔓延，投资智能开发领域，以及消除极端贫困。

In the Asia Pacific, we are modernizing alliances while making sure that other nations play by the rules -- in how they trade, how they resolve maritime disputes, how they participate in meeting common international challenges like nonproliferation and disaster relief. And no challenge -- no challenge -- poses a greater threat to future generations than climate change.

在亚太地区，我们正在与盟国建立现代化的同盟关系，同时确保其它国家在一些领域按规则行事，比如贸易、解决海洋争端以及参与核不扩散和救灾等国际共同面临的挑战等各个领域。没有任何挑战——没有任何挑战——会比气候变化对后代构成更大的威胁。

2014 was the planet's warmest year on record. Now, one year doesn't make a trend, but this does: 14 of the 15 warmest years on record have all fallen in the first 15 years of this century.

2014年是地球有气象记录以来最温暖的一年。一个年份不会形成趋势，但这个年份显示了趋势——记录上15个最温暖年份中的14个都发生在本世纪的前15年。

I've heard some folks try to dodge the evidence by saying they're not scientists; that we don't have enough information to act. Well, I'm not a scientist, either. But you know what, I know a lot of really good scientists at NASA, and at NOAA, and at our major universities. And the best scientists in the world are all telling us that our activities are changing the climate, and if we don't act forcefully, we'll continue to see rising oceans, longer, hotter heat waves, dangerous droughts and floods, and massive disruptions that can trigger greater migration and conflict and hunger around the globe. The Pentagon says that climate change poses immediate risks to our national security. We should act like it. (Applause.)

我听说一些人无视证据地说，他们不是科学家，我们没有足够的资料依据来采取行动。我也不是科学家，但是你知道吗？我认识很多来自美国航空航天局、美国国家海洋和大气管理局，以及主要大学的优秀科学家，世界上最杰出的科学家都在告诉我们，我们的行为正在改变气候，如果不采取有力行动，我们将目睹海平面上升，热浪温度更高、更持久，干旱和洪水更险恶等重大灾难，导致全球更大规模的迁徙、冲突和饥荒。五角大楼说，气候变化给国家安全带来直接威胁，我们应该相应采取行动。

And that's why, over the past six years, we've done more than ever to combat climate change, from the way we produce energy to the way we use it. That's why we've set aside more public lands and waters than any administration in history. And that's why I will not let this Congress endanger the health of our children by turning back the clock on our efforts. I am determined to make sure that American leadership drives international action. (Applause.)

正因为如此，过去6年来，为了应对气候变化，我们从生产能源的方式到使用方式，都付出了前所未有的努力。正因为如此，我们比历史上任何一届政府拨出的公用土地和水源都多。正因为如此，我们不允许本届国会开历史倒车，威胁我们下一代孩子的健康。我决心要确保美国政府推动国际行动。

In Beijing, we made a historic announcement: The United States will double the pace at which we cut carbon pollution. And China committed, for the first time, to limiting their emissions. And because the world's two largest economies came together, other nations are now stepping up, and offering hope that this year the world will finally reach an agreement to protect the one planet we've got.

我们在北京做出了一项历史性声明——美国将减排幅度加倍，中国也第一次承诺减排。正因为世界上两个最大的经济提合作，其他国家也正在加快步伐，为全球今年最终就保护我们唯一的地球达成协议提供了希望。
