Let's get one thing right:
If you're going to quote what may be FDR's most famous remark, at least quote him accurately. FDR said "December 7th, 1941 a date
which will live in infamy," not "a day...that..." I presume he didn't say "day" because, as a Groton grad, he was well aware of the difference between "day" and "date"
-- a difference that, frankly, fifth graders should comprehend and apply -- and because he found it important to speak with precision and use words that correctly and accurate depict the thoughts he cared to express.
The fact of Pearl having been bombed on a given date is why National Pearl Harbor Remembrance Day is always on a given date, December 7th, and not a given day (Mon, Tues, Wed, etc.).
You're misstating FDR's remarks does not preclude my knowing what you've got in mind. I'm merely saying that if you're going to quote someone, exhibit the rigor, the intellectual and pragmatic integrity of bothering to accurately do so. The misquote you've penned, if one takes it as representationally/existentially faithful, implies that FDR was either ignorant of the difference between "day" and "date" or too indolent to dictionally apply the difference. FDR was neither for he did indeed "know words," "have the best words" and aptly and ably use them.
With that out of the way....
- Who, in your mind, is "we?"
- Given that Congress established December 7th as National Pearl Harbor Remembrance Day and that legislation requests that the POTUS...
- "...issue each year a proclamation calling on-
the people of the United States to observe National Pearl Harbor Remembrance Day with appropriate ceremonies and activities; and
- all departments, agencies, and instrumentalities of the United States Government, and interested organizations, groups, and individuals, to fly the flag of the United States at halfstaff each December 7 in honor of the individuals who died as a result of their service at Pearl Harbor.
How do you reckon that the "'date that will live in infamy' has largely been forgotten?"
