Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_203_234 ( id number, "description" text, "total" number, "poland" number, "baltic states(resettled in poland during war)" number, "resettled in poland during war(from ussr and romania)" number, "sudetendeutsch" number, "se europe\n(hungary, romania, yugoslavia & slovakia)" number )

### Question ###
what is the difference between suicides in poland and sudetendeutsch ?

### Accurate SQL ###

SELECT (SELECT "poland" FROM table_203_234 WHERE "description" = 'suicides') - (SELECT "sudetendeutsch" FROM table_203_234 WHERE "description" = 'suicides')
