The Patriotic Act and putting Americans of Japanese descent in jail during World War II are both ways that peace was kept at home. After the attacks on September 11, 2001, the Patriotic Act was passed in 2001.
In the Preamble of the United States Federal Constitution, the phrase “ensuring domestic tranquilly” is used. It talks about ways to keep the peace between or in the U.S. communities.
Some good examples of making sure there is peace at home are what President John F. Kennedy and his administration did to protect civil rights and end the Civil War. Even though the U.S. Supreme Court said that separating students by race in public schools was against the law, not all public schools followed the decision. Kennedy signed Executive Orders 10925 and 11063 to make sure that civil rights were respected.
