Answer:
Historian Ronald Takaki titled a section of his book "Japanese Americans: A tremendous Hole in the Constitution" to highlight the discriminatory treatment of Japanese Americans during World War II, when they were subjected to forced relocation and internment in camps by the United States government.
Takaki uses the term "tremendous hole" to emphasize the contradiction between the Constitution's promise of equal protection under the law and the violation of Japanese Americans' civil liberties. The forced relocation and internment of Japanese Americans during World War II was a result of racism and fear, and it represented a significant failure of the American democratic system to protect the rights of its citizens.
The title of the section reflects Takaki's belief that the government's actions during this period were a betrayal of the principles upon which the United States was founded and a serious breach in the protections offered by the Constitution.
