Why did the British think the war was going to be over quickly?

They are kind of conceded

Explanation:

The british at the time always thought that they were the best and that nothing and no one could beat them. When they joined in WW1, they were promptly put in retreat and then dug trenches across europe. In WW2, they thought that since Hitler was not supposed to have a large army, he would not dare attack anyone that Britain was protecting. They were wrong.

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.
