Manzanar teaches about Japanese American incarceration in the US. That’s in jeopardy under Trump

As visitors to the national historic site are urged to inform on anything negative', advocates warn of the same playbook that led to concentration camps

At the eastern slope of the Sierra Nevada, more than 200 miles (320km) outside Los Angeles, in what feels like the middle of nowhere, is Manzanar national historic site. It marks the place where more than 10,000 Japanese Americans were incarcerated during the second world war, crowded into barracks, surrounded by barbed wire and guard towers with searchlights, and patrolled by military police.

Since then, Manzanar, which now has a museum and reconstructed barracks that visitors can walk through, has been transformed into a popular pilgrimage destination for Japanese Americans to remember and teach others about this history. (Manzanar was one of 10 concentration camps where the US government forcibly relocated and held more than 110,000 people of Japanese descent during the second world war.)
