Pledge Ruled unconstitutional

A federal appeals court has ruled the Pledge of Allegiance to be as it endorses religion. (Found via InstaP)
Interesting. I seem to recall that the “under God” portion of the Pledge — which I presume was the part causing the court heartburn — was only added in recent times. I want to guess at the President, but I’ll surely get it wrong — but I think it was somewhere between 1950-1970. Little help, anyone?
Anyway, assuming the ruling stands, does that mean we should just go back to the old pledge, sans deity?
Update: Folks have written in to contribute that the year was 1954; the President was Eisenhower. Michael Hankamer also notes the following:
“This version of the Pledge of Allegiance was taken from the CNN website. Now I could be wrong, but it seems to me that CNN – and the Court (?) – has lost a comma.
“I pledge allegiance to the flag of the United States of America, and to the Republic for which it stands, one nation under God, indivisible, with liberty and justice for all.”
Correctly, it should read:
“I pledge allegiance to the flag of the United States of America, and to the Republic for which it stands, one nation, under God, indivisible, with liberty and justice for all.”
Silly pro journos. “Professional Fact Checking” indeed…
