They don't care. No one is punishing them for not complying with releasing all of the Epstein files, and no one is going to punish them for anything in those files. Jeffrey Epstein was the first and likely last person to suffer any consequence beyond reputational harm.

There are numerous reasons why the US will probably go to war with Iran at some point (it's part of the "Axis of Evil" after all) but distracting from Epstein isn't one of them.
