福克斯新闻 奥巴马概述了相关外交政策计划

President Obama telling the nation's newest commissioned officers the U.S. must always lead on the world stage.

(President Obama) "The military that you have joined is and always will be the backbone¹ of that leadership."

But, the President cautions, military action cannot be the only or even the primary component² to solving international challenges.

(President Obama) "Some of our most costly³ mistakes came not from our restraint, but from our willingness to rush into military adventures without thinking through the consequences."

President Obama says he'll work with Congress to increase assistance to rebels fighting in Syria, and establish a fund to support other nations' fights against terrorism.
