O. I. L. ?
Amy Goodman of Democracy Now speculated on the Majority Report Radio show over Air America that the original name of Operation Iraqi Freedom was Operation Iraqi Liberation, but when someone spelled out the acronym ...
Also, I saw a commercial on the Sunday morning pundit shows created by B.P. which used to mean British Petroleum but now means Beyond Petroleum.
Interesting what we can learn and infer from a few simple acronyms.
