What is the analysis of "Bitter strawberries" by Sylvia Plath?

"Bitter Strawberries," by Sylvia Plath, describes a
conversation that takes place among farm workers who are picking
strawberries.

The conversation is about "the Russians," who
pose a threat to the farmers' country, which is presumably the U.S.A. (The poem was
first published in 1950, when fear of Communist Russia was rampant in
American.)

One woman, who is identified as "the head
woman," takes a militant stance against the Russians.  "'Bomb them off the map,'" she
says, and "'We ought to have bombed them long ago.'"

The
head woman's opinion is opposed by Mary, who is concerned about her "fella" (boyfriend)
who is "'Old enough to go [war] / If anything should happen...'"  The head woman is also
opposed by a little girl who says, "'I can't see why / You're always talking this
way.'"

The head woman ends the discussion by ordering
everyone, in a "businesslike" tone, to go back to work.  The workers return to their
task, and seem to be absorbed by it:

Kneeling over the rows,
We reached
among the leaves
With quick practiced hands,
Cupping the berry
protectively before
Snapping off the stem
Between thumb and
forefinger.

On one level, the
poem can be seen as a discussion of xenophobia, the fear of
foreigners.

On another level, it can be seen as a
reflection on how the routines of life continue, despite the fact that many larger,
ominous questions remain unanswered.  On this level, the poem reminds me of "Out, Out"
by Robert Frost, in which a boy is killed in a freak accident, and his family and
neighbors quickly go back to their routines.
