Bull. This is the United States of America. Government employees should NEVER communicate with anyone in any language but English EVER.
Why don't you shag yourself down to Gitmo and start interrogating some of the terrorists there in English, come back when you've gotten some information.
We live in a world and interact with many foreign nations, we need to communicate in order to conduct the business of a nation.
It isn't globalism, it's good, solid business sense.
