Francophobia in... the Post Office?

Today I went to the Post Office to mail our taxes to the IRS. The line was long, and in boredom I looked at the forms for international shipments: customs forms, return receipts, etc. Much to my surprise, I found that the customs forms (printed January 2004) are now exclusively in English.

If I recall properly, the Universal Postal Union conventions, dating from the mid-19th century, require that international postal forms be available in local language and French. (This was how I managed to properly fill out some forms when I was mailing some books home from Hungary in the early 90s.)

The forms printed in pre-Bush days are in both languages.

Was the Post Office directed to remove the French? Did they do it on their own initiative? Did the UPU rules change so that French is no longer required?
