What are two reasons the United States wanted to stop the spread of communism

1. Its not healthy because some people need things that others don't (EX; A skinny person and an overweight person)

2. America was built on the rights of the people

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.

what are the options?
