whether… or~
Expresses that two listed alternatives both lead to the same conclusion, similar to 'whether... or...' in English.
This pattern presents two contrasting options and states that regardless of which one applies, the result is the same. It is somewhat formal and is used in both speaking and writing, though more common in written or careful speech. The pattern can also be used with only one item (Aにしろ) to mean 'even if' or 'whether or not', but the paired form is the most common and is the focus here. It often appears with expressions like '同じだ' or '変わりはない' to emphasize the equal outcome.
