Which is the Best Language to Learn?

Intelligent Life:

For language lovers, the facts are grim: Anglophones simply aren’t learning them any more. In Britain, despite four decades in the European Union, the number of A-levels taken in French and German has fallen by half in the past 20 years, while what was a growing trend of Spanish-learning has stalled. In America, the numbers are equally sorry. One factor behind the 9/11 attacks was the fact that the CIA lacked the Arabic-speakers who might have translated available intelligence. But ten years on, “English only” campaigns appeal more successfully to American patriotism than campaigns that try to promote language-learning, as if the most successful language in history were threatened.
Why learn a foreign language? After all, the one you already speak if you read this magazine is the world’s most useful and important language. English is not only the first language of the obvious countries, it is now the rest of the world’s second language: a Japanese tourist in Sweden or a Turk landing a plane in Spain will almost always speak English.
