I'm old enough...
to remember Red, and Milton, and Sid, and Jimmy and the overwhelming patriotism and love of country that permeated the country, then. The words "under God" were added in 1954, as a statement of solidarity and unity in the face of the Communist enemy. That goverment forbad any reference to God, and alliegience to ANY religion.
Today, we are faced with enemies no different than the communists, but who still dictate whom you shall worship, how you shall dress, what you shall eat, and provide absolutely no freedoms whatsoever.
Now, does this answer any questions about why we include "Under God" in our pledge? Kind of important , eh?
You are not under any duress to say the words "under God' when you pledge alligience, and that is what makes our country great, and our enemies furious!
Oh by the way, the other thing which makes our country great, is that those who chose not to believe in God, have absolutely no right to dictate what those of us who believe in God, to recite in our pledge to our country's flag. We don't force you to say it our way, do we?
