While the internment of more than 100,000 Japanese-Americans early in America's entry into WWII was a harsh measure, it is better understood in context with

Japanese internment camps were established during World War II by President Franklin Roosevelt through his Executive Order 9066. From 1942 to 1945, it was the policy of the U.S. government that people of Japanese descent would be interred in isolated camps. Enacted in reaction to Pearl Harbor and the ensuing war, the Japanese internment camps are now considered one of the most atrocious violations of American civil rights in the 20th century.

Explanation:

The internment of Japanese Americans in the United States during World War II was the forced relocation and incarceration in concentration camps in the western interior of the country of about 120,000 people of Japanese ancestry, most of whom lived on the Pacific Coast. Sixty-two percent of the internees were United States citizens.These actions were ordered by President Franklin D. Roosevelt shortly after Imperial Japan's attack on Pearl Harbor.

Of 127,000 Japanese Americans living in the continental United States at the time of the Pearl Harbor attack, 112,000 resided on the West Coast.About 80,000 were Nisei (literal translation: "second generation"; American-born Japanese with U.S. citizenship) and Sansei ("third generation"; the children of Nisei). The rest were Issei ("first generation") immigrants born in Japan who were ineligible for U.S. citizenship under U.S. law.

Japanese Americans were incarcerated based on local population concentrations and regional politics. More than 112,000 Japanese Americans living on the West Coast were forced into interior camps. However, in Hawaii, where 150,000-plus Japanese Americans composed over one-third of the population, only 1,200 to 1,800 were also interned. The internment is considered to have resulted more from racism than from any security risk posed by Japanese Americans.California defined anyone with 1/16th or more Japanese lineage as sufficient to be interned.Colonel Karl Bendetsen, the architect behind the program, went so far as saying anyone with "one drop of Japanese blood" qualified.

Roosevelt authorized Executive Order 9066, issued on February 19, 1942, which allowed regional military commanders to designate "military areas" from which "any or all persons may be excluded."[16] Although the executive order did not mention Japanese Americans, this authority was used to declare that all people of Japanese ancestry were required to leave Alaska and the military exclusion zones from all of California and parts of Oregon, Washington, and Arizona, except for those in government camps. Internment was not limited to those of Japanese ancestry, but included a relatively smaller number—though still totalling well over ten thousand—of people of German and Italian ancestry and Germans deported from Latin America to the U.S.:124 Approximately 5,000 Japanese Americans relocated outside the exclusion zone before March 1942,while some 5,500 community leaders had been arrested immediately after the Pearl Harbor attack and thus were already in custody.

the process is called revolution because it was a process of great economic-social transformations that began in england in the xviii century.

the industrial mode of production spread throughout much of the northern hemisphere throughout the xix and early xx centuries.

the effect of this revolution was the distance between the countries, with respect to economic and political power.   after all, not all industrialized at the same time, remaining in the condition of suppliers of raw materials and agricultural products to the industrialized countries.

these differences mark to this day the nations of the world that are divided between developed and developing countries. one way to measure whether a country is advanced is to assess how industrialized it is.
