Dad, how do soldiers killing each other solve the world's problems?

No war, or battle’s sound
Was heard the world around.
The idle spear and shield were high up hung.

I have discovered that all human evil comes from this, man’s being unable to sit still in a room.

Glory to God in the highest, and on earth peace, good will toward men.

We the people of the United States, in order to form a more perfect Union, establish justice, insure domestic tranquillity, 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.
