International DDoS busts and arrests do happen all the time.

Law enforcement takes time. The perpetrators of these attacks aren't hanging out in the open with their full names shielded only by the hope that their country won't extradite for political favor.

By the time the perpetrators are identified and a case is built, getting them charged isn't bottlenecked on the lack of an international agency. Any international law enforcement agency would be beholden to each country's own political wills and ideals, meaning any "teeth" they had would be no more effective than what we currenly have for extraditing people or cooperating with foreign police organizations.
