We tried to bring both the Nationalist and Communist leaders together to come to some form of Compromise. We also left a delegation in Nanking to work with the new Communist regime, instead of fleeing back to Taiwan. China and Russia would soon fight over the fundamentals of Communism.

George Washington did not want to accept the presidency that the people wanted to give him for fear of becoming a tyrant himself, just like King George II of England, from whom they just declared themselves independent from. When he became president, he made an example by only taking 2 terms and then refusing to continue being president. It wasn't until much later that a law was introduced to prevent any single president from serving more than 2 terms.
