Describe the imbalance of trade that occurred in the year after 1810

The imbalance of trade that occurred in the year after 1810 in the U.S. was as a result of the foreign trade that was severely disrupted by Jefferson’s trade embargo, the British blockade during the 1812 War and consequent non-importation measures. The disruptions barred foreign manufactured goods from getting to the U.S. markets that gave protection to nascent domestic industries from import competition. This gave rise to the establishment of new manufacturing firms while existing domestic producers rapidly expanded output to replace previously imported goods.

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.
