. . . a document was published that began thus:
"When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation."
This action was the official beginning of unpleasantness between us and our (now) friends in the British Empire - an unpleasantness that lasted (again, officially) until 1815. During that time, we had the unfortunate need to declare war on Britain not once, but twice.
Feelings between us have moderated a bit since then, and I shall be eternally grateful that they have remained so.
Our Navy still flies a jack based on one from that era. Whatever the opinion of the U. S. in the world today, the flag still contains some good advice.
