(To help your understanding, refer to the Victor Cha's figure below) Multilateralism, whether in the form of membership in anr in international institutions,to bind the great power, discourage unilateralism, and give the small powers a voice and voting opportunities that they would not otherwise have.
I use milk or half and half or even coffeemate creamer in strong black teas. I use 1 tsp to 10 or so fluid ounces of tea or 2 tsp to a 16 oz cup. Tea waters down a lot more than coffee and when I first tried lightener in tea, I found it awful. Overpowering and like milky water. I was using way too much.
Sweetening is up to personal taste. If you put 1 tsp of sugar in a 10 oz mug of tea, then multiply that by 12.8 to get the mathematical amount for 1 gallon. Dont add the sugar until the tea has completely steeped, because it can slow or even stop the process. Honey is good in green tea, too.
