Explain one way in which international relations in the period 1900-1945 changed as a result of japanese policies

Before modernization of Japan, it was easily subdued by foreign powers. It was highly skeptical of colonial powers of Britain and France and was also not happy about the presence of United States in the Pacific.

After the Meiji Restoration period, Japan had not only developed an advanced, export led economy, it was able to muster a regional military force which had warships, guns, and fighter planes.

Japan had a new found confidence in it's abilities and sought to challenge regional players for dominance.

Britain, China, Russia all posed some form of a threat to Japan, which the rulers believed should be eliminated for Japan to prosper.

Eventually, Japan became involved in Wars with major powers which they eventually lost in 1945.
