I believe you're wrong on this one. We are a Nation, AND a Republic.
We are a nation, the third largest nation in the world (land wise). One Nation, under God ..
Check Wikipedia and the dictionary - both refer to the United States as "a nation"
What logic or what proof do you have that says the United States is NOT a Nation?
U.S. Constitution, Article 4, Section 4... Section. 4.
Quoted Text
The United States shall guarantee to every State in this Union a Republican Form of Government, and shall protect each of them against Invasion; and on Application of the Legislature, or of the Executive (when the Legislature cannot be convened), against domestic Violence.
Country, State, and Nation Definining an Independent Country
Updated October 05, 2011 While the terms country, state, and nation are often used interchangeably, there is a difference. A State (note the capital "S") is a self-governing political entity. The term State can be used interchangeably with country.
A nation, however, is a tightly-knit group of people which share a common culture. A nation-state is a nation which has the same borders as a State.
States and Independent Countries
Let's start with what defines a State or an independent country. An independent State:
Has space or territory which has internationally recognized boundaries (boundary disputes are OK). Has people who live there on an ongoing basis. Has economic activity and an organized economy. A country regulates foreign and domestic trade and issues money. Has the power of social engineering, such as education. Has a transportation system for moving goods and people. Has a government which provides public services and police power. Has sovereignty. No other State should have power over the country's territory. Has external recognition. A country has been "voted into the club" by other countries. There are currently 196 independent countries or States around the world. Territories of countries or individual parts of a country are not countries in their own right. Examples of entities that are not countries include: Hong Kong, Bermuda, Greenland, Puerto Rico, and most notably the constituent parts of the United Kingdom. (Northern Ireland, Wales, Scotland, and England are not countries.)
A "state" (with a lower-case "s") is usually a division of a federal State (such as the states of the United States of America).
Nations and Nation-States
Nations are culturally homogeneous groups of people, larger than a single tribe or community, which share a common language, institutions, religion, and historical experience.
When a nation of people have a State or country of their own, it is called a nation-state. Places like France, Egypt, Germany, and Japan are excellent examples of nation-states. There are some States which have two nations, such as Canada and Belgium. Even with its multicultural society, the United States is also referred to as a nation-state because of the shared American "culture."
There are nations without States. For example, the Kurds are stateless people.
Also, I continued to look for a bit more proof, but at this time, I cam across a source that you believe, Wikipedia, that shows that the Pledge of Allegiance, as originally written, was a marketing ploy... by a socialist, Francis Bellamy, who was the cousin of socialist utopian novelist Edward Bellamy.
The Pledge of Allegiance was written in 1892 by Francis Bellamy (1855–1931), who was a Baptist minister, a Christian socialist, and the cousin of socialist utopian novelist Edward Bellamy (1850–189. The original "Pledge of Allegiance" was published in the September 8 issue of the popular children's magazine The Youth's Companion as part of the National Public-School Celebration of Columbus Day, a celebration of the 400th anniversary of Christopher Columbus's arrival in the Americas. The event was conceived and promoted by James B. Upham, a marketer for the magazine, as a campaign to instill the idea of American nationalism by selling flags to public schools and magazines to students.[3][4][5][6] Bellamy's original Pledge read as follows:[7] I pledge allegiance to my Flag and the Republic for which it stands, one nation indivisible, with liberty and justice for all.
Students swearing the Pledge on Flag Day in 1899 The Pledge was supposed to be quick and to the point. Bellamy designed it to be recited in 15 seconds. As a socialist, he had initially also considered using the words equality and fraternity[6] but decided against it - knowing that the state superintendents of education on his committee were against equality for women and African Americans.[8] Francis Bellamy and Upham had lined up the National Education Association to support the "Youth's Companion" as a sponsor of the Columbus Day observance along with the use of the American flag. By June 29, 1892, Bellamy and Upham had arranged for Congress and President Benjamin Harrison to announce a proclamation making the public school flag ceremony the center of the Columbus Day celebrations (this was issued as Presidential Proclamation 335). Subsequently, the Pledge was first used in public schools on October 12, 1892, during Columbus Day observances organized to coincide with the opening of the World's Columbian Exposition in Chicago, Illinois.[9]
