Holocaust Poetry #2

Homeland
Lois E. Olena

It was Christmas eve
and there was no room in the inn,
the Oswiecim inn,
so the Arrow Cross
took the children,
barefooted
and in their nighties,
out to the Danube
and filled their little bellies
not with bread
but bullets
flipping them
like tiddlywinks
into the congealing, icy river below.

It was the Red Danube
that night,
choking on the blood
of orphan Jews
whose little Blue faces
floated downstream
touring even all of Europe
until they washed up
on the shores of Eretz Yisrael (Jewish homeland)
and came back to life,
their little blue and white
bodies
raised high,
flapping in the wind.
How is imagery used in this poem?
Imagery is used by describing there death, without actually saying it. The author uses descriptive words to tell us they're dead, e.g. 
and filled their little bellies not with bread but bullets.
Discuss the effect of the simile in this poem.
The simile " flipping them like tiddlywinks" shows that the Nazi's "played" around with the Jews and just killed them like it was nothing.  
How is alliteration used in the poem? What is the effect?
Alliteration is used with " bellies not with bread but bullets" and the effect is that it makes it more noticeable and stronger.
How does the author juxtapose the innocence of the children to the cruelty they experienced?
not sure..  
What is meant by 'touring all of Europe'? It means that they floated in the rivers and not one picked them up or bothered and they went all around Germany, in a greater meaning i assume it means this happened everywhere in Germany and other places.
