Explanation
にしろ~にしろ is used to present two or more alternatives and say that the statement applies regardless of which of those options is chosen. It highlights that the result or situation is the same no matter which side of the dichotomy/event is true. It’s often used to point out that the outcome or decision will be affected by either option in a similar way, or to request consideration of both possibilities. The two sides can be nouns, verbs, or adjectives, and the first and second items are connected by にしろ ... にしろ. It carries a nuance of inevitability or inevitability of consequence across alternatives, sometimes with a sense of frustration or resignation depending on context.
