In all likelihood the attack didn't originate from N Korea. Therefore responding to N. Korea is a mistake. Also the US government doesn't have the authority to protect the international interests of a multi-national company, against another national, or extra-national threat. Warships don't escort private ships traveling in hostile waters. The private ship may request assistance if and when it is needed, but then assistance is granted at the discretion of the chain of command. Naturally if the private ships are contracted to the military, its slightly different. Likewise the government may catch a spy, charge them, and deal with the diplomatic fall out. But insofar as returning the documents that were stolen, or installing new door locks to keep spies out. That oversteps its authority. :.:.: Blaming N. Korea gives a lot of 3 letter agencies a bigger budget. And right now when budgets are being written, and analyzed as the fiscal year is ending its time to play those cards.
