Do you believe japanese internment during WWII was necessary to protect national security?

Answers

Answer:

Explanation:

I live in Canada. Exactly the same thing was done here as was done in America. I have lived in two places where the internment took place. One of them is in the midst of suing the Canadian Government for what was done to them. In the other the people did their best to blend in with the community. Most people are satisfied that they did.

One of our Federal political parties argued that it was totally unnecessary and the rights of those who were interred and had Canadian Citizenship had their rights violated. The Japanese in the first community will never vote for any party but the one that defended them.

I am among those who believe that it was an unjust, unnecessary act. I think it was wonderful that the second group could blend in. One of the cites you should never miss is the Japanese garden. The girls employed in that place are all dressed in Kimonos which are floor length and made of the finest silk.

Most of the people who were interred lived on the coast. They were fisher people when they came to Canada and that's how most of them made their living. They were peaceful honest hospitable and clean. They did nothing but contribute to the richness of Canadian Culture. They should never have been interred.

Answers

Answer:

Montesquieu was a French lawyer, man of letters, and one of the most influential political philosophers of the Age of Enlightenment. His political theory work, particularly the idea of separation of powers, shaped the modern democratic government.

George Washington Carver

PHOTOGRAPH BY UNIVERSAL HISTORY ARCHIVE / UNIVERSAL IMAGES GROUP VIA GETTY IMAGES

Carver was born an enslaved person in the 1860s in Missouri. The exact date of his birth is unclear, but some historians believe it was around 1864, just before slavery was abolished in 1865. As a baby, George, his mother, and his sister were kidnapped from the man who enslaved them, Moses Carver. The kidnappers were slave raiders who planned to sell them. Moses Carver found George before he could be sold, but not his mother and sister. George never saw them again.

After slavery was abolished, George was raised by Moses Carver and his wife. He worked on their farm and in their garden, and became curious about plants, soils, and fertilizers. Neighbors called George “the plant doctor” because he knew how to nurse sick plants back to life. When he was about 13, he left to attend school and worked hard to get his education.

In 1894 he became the first Black person to graduate from Iowa State College, where he studied botany and fungal diseases, and later earned a master’s degree in agriculture. In 1896, Booker T. Washington offered him a teaching position at Tuskegee Institute, a college for
