Quite an incentive for an untimely and disproportionate response to the attackers, should they be located.

Edit: Umm, humans have formed armies and started wars over far less theft and far lesser threats to their populations than this. If the attackers are located, some piano wire around their necks is really cheap in comparison. And for this amount of damage, I do not doubt for a moment that it's a consideration by every single government spy organization.
