Why did nativists want the government to bar entry to chinese immigrants ?

The anti-Chinese movement of the 19th and 20th century was created thanks to the idea that the Chinese immigrants were not integrating to the American society and that they drove wages down for the American worker. Thanks to this unions where a large factor in this conflict. This movement was so big, mostly in California, that it successfully restricted Chinese immigration into the US from 1880 until the 1940's

it's no easy i swear it's hard

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.
