While the good ole USofA has many flaws, it's probably the best country that has ever been or ever will be! You just can't do much better!
And yes, it's important to look back at the men of those times who made it happen. The signers of the Declaration of Independence pledged their "Lives, Fortunes and Sacred Honor" to the concept of America. And that was real, had we lost the war (which seemed very likely) they all would have been hanged.
I'm awed and humbled by their greatness!
