Thomas Paine wrote Common Sense. This pamphlet stated the important reasons for colonial independence from Britain. Our greatest enemy during this time was the King of England.
I think it was The Cuban missile crisis. Because the Soviet Union had given Cuba the missiles. JFK then ordered the navy to form a blockade around Cuba and the disarming of the missiles.
If that isn't an option, The Soviet Union also shot down an American U-2 spy plane of Soviet air space. But it wasn't a major conflict as the pilot and a Soviet spy were traded in an agreement.

The United States Constitution's Preamble which often referred to as "We the people." It was signed during the constitutional convention in 1787 and fully ratified in 1788, explained amongst other things that "they wanted to protect the freedoms now and for future generations to come" by stating that "...and secure the Blessings of Liberty to ourselves and our Posterity, ..."
The full preamble goes thus: "We the People of the United States, to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, AND SECURE THE BLESSINGS OF LIBERTY TO OURSELVES AND OUR POSTERITY, do ordain and establish this Constitution for the United States of America."
