Why is the tension from the late 1940s to the early 1990s between the US and the USSR considered a Cold War?

definitely a for sure. ill see and update if i get the answer

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.
