In such circumstances, we have to work with othersbecause collective action in these circumstances ismore likely to succeed

这些情况下 我们需要同他人合作原因在于 这些情况下 联合行动更有可能取得成功

more likely to be sustained less likely to lead tocostly mistakes

更有可能持久更不容易出现代价沉重的错误

This leads to my second point:

这就引出了我的第二点

For the foreseeable future the most direct threat to America at home and abroad remainsterrorism

在可以预见的未来对美国内外最大的直接威胁将仍然是恐怖主义

But a strategy that involves invading every country that harbors terrorist networks is naiveand unsustainable

但是 攻入每一个包庇恐怖分子的国家不仅天真 而且无法持续

I believe we must shift our counterterrorism strategy drawing on the successes andshortcomings of our experience in Iraq and Afghanistan

我认为 我们必须转变自己的反恐战略从伊拉克和阿富汗的战争中吸取经验教训

to more effectively partner with countries where terrorist networks seek a foothold

在恐怖分子试图立足的国家寻求有效的合作伙伴

And the need for a new strategy reflects the fact that today's principal threat no longer comesfrom a centralized al Qaeda leadership

我们的新战略必须意识到如今的主要威胁不再来自于基地组织这样的集中领导

Instead, it comes from decentralized al Qaeda affiliates and extremists many with agendasfocused in countries where they operate

而是来自于分散式的基地组织残党和极端主义者他们很多都将目标集中在自己国内

And this lessens the possibility of large-scale 9/11-style attacks against the homeland

这就减弱了美国本土遭受大规模 911式袭击的可能性

but it heightens the danger of U.S. personnel overseas being attacked as we saw in Benghazi

但美国人员在海外受到攻击的威胁却因此增大班加西的情况就是明证

It heightens the danger to less defensible targets as we saw in a shopping mall in Nairobi

防御薄弱的目标比以往更加危险内罗毕商场的情况就是明证

So we have to develop a strategy that matches this diffuse threat one that expands ourreach without sending forces

我们的新战略需要考虑到这些分散式威胁在不派遣部队的前提下扩大作用范围

that stretch our military too thin or stir up local resentments

这样既能保持军队的集中作战能力又能避免激起当地不满情绪
