uh huh...........and from the pledge of allegiance.............
In its original form it read:
"I pledge allegiance to my Flag and the Republic for which it stands, one nation, indivisible, with liberty and justice for all."
In 1923, the words, "the Flag of the United States of America" were added. At this time it read:
"I pledge allegiance to the Flag of the United States of America and to the Republic for which it stands, one nation, indivisible, with liberty and justice for all."

most likely what you cited was the us intentionally "dumbing" things down as most don't know what a republic is.
lastly, whatever some tin pot dictator wants to call his backwards country should have no bearing on the usa being a republic.
