<p>Learning a language is a major commitment, so it’s good that you’re giving some thought to which language you’d like to learn. Obviously, a language can help you further your career objectives, but I’m skeptical about how clear those can be for someone who’s just finishing high school. Here is how I would decide:</p>
<p>1) Is there a particular country in which you have a strong interest? A particular culture whose movies/films/books you greatly enjoy? If so, learn the language of the that country or culture. Passion goes a long way, and any language can help you with some things.</p>
<p>If and only if you have no particular passion, then think about the following:</p>
<p>2) Are you interested in a business career? If so, then the logical choices are Chinese, German, or Japanese </p>
<p>3) Are you interested in international security/a career with the CIA/NSA/Department of Defense, etc.? If so, the logical choices are Arabic, Persian (Farsi), Korean, Russian, or Chinese</p>
<p>4) Are you interested in international organizations such as the UN? If so, the logical choice is probably French</p>
<p>5) Are you interested in a particular region of the world? Spanish is best for the Americas, French for Africa, Arabic for the Middle East/North Africa, Russia for the former Soviet Union, etc.</p>
<p>6) Are you interested in a particular sort of history? E.g., Latin for the ancient world</p>
<p>There are many other questions, but those are a few of the ones to consider. I can’t emphasize enough, though, that you need to take a language that interests you and that is spoken by people who interest you. It’s very hard to get through a language you don’t care about.</p>
<p>As for the Arabic v. Chinese dilemma, I think it’s simple. IF you’d enjoy Arabic more, take it more. Even IF (not when) US involvement in the Middle East declines, it won’t be like after the end of the Vietnam War when there was suddenly no need for Vietnamese speakers. Arabic is spoken by half a billion people (280m or so as a first language) putting in the global top 5. It’s an important language not just for security and terrorism, but also for business (particularly oil, but also in other areas as Dubai emerges as a financial center and the ME generally develops more), history, and culture.</p>
