であれ

であれ is a formal, literary ending attached to nouns or nominal phrases to express strong inevitability: “no matter what/how,” or “even if it is X.” It is more solemn and emphatic than the everyday ても. It tends to appear in written prose, speeches, or opinionated statements, and it often conveys a rule-based or universal tone. Typical usage is after a noun or noun phrase to indicate that the following statement applies to all cases of that noun. Note that this form is more common in formal or rhetorical contexts and sounds unnatural in casual conversation.
