...internment camps during World War II.

Hello Alan, Mister Micawber, Beeesneees, Mordant and other native English speakers,

California’s Japanese Americans still smart under the memory of internment camps during World War II.
[This is a sample sentence from a vocabulary book, so there’s no context I can provide you with.]

Does this sentence sound good to you?

  • …internment camps during World War II.
  • …internment camps [color=red]used during World War II.
    Does the second sound better?

The sentence sounds appropriate as it is, Tofu.

It is the entire memory of the World War II internment camps that causes the upset, not just the fact that they were used (by any side).

Personally, I would be tempted to rearrange the ending:
“… under the memory of World War II internment camps.”

Thank you, B.
