Multiple reports say American officials are promising that the country will respond to the Sony Pictures hack, allegedly perpetrated by North Korea, that pushed the studio to cancel the release of the Seth Rogen-James Franco movie The Interview. Reuters says the promised retaliation wll be "forceful." How does one respond, though, to an economically damaging attack against a movie studio carried out by a country that doesn't have an entertainment industry and is already subject to heavy sanctions? CNN writes that there is, in fact, still potential to put economic pressure on the hermit kingdom:
The toughest option: The United States could restrict North Korea's dollar-denominated trade by hitting Chinese banks that do business with Pyongyang -- a tactic used against Iran and, less comprehensively, against Russia after its incursion into Ukraine's Crimea region.
A CNBC piece elaborates on that option, suggesting specific companies working inside the country could be sanctioned.
Firms working with North Korea include Egyptian telecom Orascom, which reportedly just earned $500 million from its work to provide cellular service to more 2 million North Koreans. Even Chinese companies operating in the country could be targeted, experts said, although sanctions against these firms could result in consequences that spill beyond the Korean peninsula.
In general, CNBC writes, China's influence on North Korea could make it something of a fulcrum for the United States response; North Korea might not care what the United States thinks of it, but it cares about China, and China in turn cares about its relationship with the U.S.
Ultimately, the best strategy for retaliation against Pyongyang may be to lean on China, said Bruce Bennett, a senior defense analyst at Rand Corp. If the U.S. can establish sufficient evidence that Beijing either trains or provides resources to North Korean hackers, the government would do well to threaten China with accessory charges to the Sony hacking, he said.
Additionally, government representatives could emphasize that North Korea is upsetting China's goal of regional stability. Beijing would likely be able to sway Pyongyang's hacking policies, as Chinese firms account for much of North Korea's foreign investment.
As of yet, the United States hasn't even officially identified North Korea as the entity responsible for the hack—though CNN reports that could happen as early as today.
