Poetry Anthology-The Emigree theoryWatch
In the next stanza, the narrator describes how 'time rolls its tanks' which could be reference to the battle of Oder–Neisse which was believed to be the victory to 'break through the gates of Berlin'. In the battle the soviets used 20,000 tanks and in world war 2, tanks were used to alot more effect than they had been used in the first world war. 'Banned by the state' could refer to the fact that West Germany banned the Nazi party from ever forming and Denazisation that followed shortly after the war or the idea that East Berlin was well known for shutting down free speech and arresting political opponents using a secret police.
In the third Stanza, the narrator talks about how she cant go back as she has 'no passport.' And how the city takes her dancing through the 'city of walls'. This could be an obvious nod to the Berlin Wall and how there was extreme travel restrictions both to enter East Berlin and to leave East Berlin, the narrator is likely a West German though as most people who ran from Germany in the exodus were running from communism in the east. 'They accuse me of absence' and 'they circle me' all show the slow resentment to nazism that came from denazisation in Germany following the world war years.
