とあれば — “if it's a case of, given that”
Says that if a particular important condition holds, an otherwise unusual action becomes justified
Noun (or plain-form clause) + とあれば sets up a condition that, if true, is important enough to justify going to unusual lengths — “if it's a matter of X, (then anything is worth doing).” It carries a sense of strong motivation or determination once that condition is met.

Watch out
とあれば signals that the named condition is important enough to justify extreme measures — it reads oddly attached to a trivial, low-stakes condition, where plain なら is the more natural choice.
