"In the matter of reforming things, as distinct from deforming them, there is one plain and simple principle: There exists in such a case a certain institution or law; let us say, for the sake of simplicity, a fence or gate erected across a road. The more modern type of reformer goes gaily up to it and says, ‘I don’t see the use of this; let us clear it away.’ To which the more intelligent type of reformer will do well to answer: ‘If you don’t see the use of it, I certainly won’t let you clear it away. Go away and think. Then, when you can come back and tell me that you do see the use of it, I may allow you to destroy it.’" — G.K. Chesterton
We hear a great deal about how America needs to be "changed" by people who don't seem to know America's history, understand our country's uniqueness, or appreciate how good we've had it as a people. Until you understand what made America a great nation to begin with, you have no business suggesting any changes to the policies, tradition, and culture that made us so uniquely successful. It's not an accident that America became a great power. It's because of these seven reasons.
1) Judeo-Christian Ethics: When people call America a "Christian nation," they're referring to the Judeo-Christian morals that shaped our country. Our strong sense of right and wrong kept corruption to a minimum, our Protestant work ethic caused Americans to be productive, and our belief in rights given by God, not government shaped our national philosophy. Respect for Christian values is a part of the fabric of our country that goes right back to our founding. Even if many people wouldn't realize it until it is too late, an America where Christianity isn't an important part of everyday life would no longer be America in any meaningful sense.
2) A Powerful Military: There's a lot to be said for "soft power," but it pales in comparison to raw military might. The United States was not always a great military power, but once the Civil War was over, we started to assert ourselves. Since WWII, we've had the finest military on Planet Earth. That one factor does more to insure our freedom and the safety of our allies than every other factor combined. As Reagan said, "History teaches that war begins when governments believe the price of aggression is cheap." At least for now, no nation could be so foolish as to believe that a potential fight with the United States would be cheap.
