Clearly if you are asking this question you don’t understand the Preamble so I’m going to list the reasons first:
1. Establish justice
2. Ensure domestic tranquillity
3. Provide for a common defense
4. Promote general welfare
5. Secure the blessings of liberty to ourselves and our posterity
So, in my opinion, these are ones I would add if I were to make the Preamble.
We the people of the United States order a perfect Union to insure...
1. Police brutality is just as bad as brutality against police
2. The elimination of wage gap between races and genders of man and woman
3. The union to unite and adore their country; to hate the government instead of the country
