What did the government know would happen next in world war 2?

As World War II progressed, governments, particularly the Allies, anticipated that the conflict would intensify, leading to more destructive battles and higher casualties. They understood that the Axis powers, particularly Nazi Germany and Imperial Japan, would likely continue their aggressive expansion, prompting a need for strategic military responses. Moreover, there was an awareness that the war would eventually require significant sacrifices on the home front, including economic mobilization and civilian involvement. Intelligence efforts also indicated that the use of advanced weaponry, such as atomic bombs, would change the nature of warfare and could hasten the conflict's conclusion.
