People keep trying to diminish the possibility that North Korea was behind the attack on Sony, which I don’t get. An online attack is not like a nuclear weapon, needing a massive capital investment and scarce domain expertise. Computer experts are much easier to develop, and the investment to make such attacks is well within the budget of even a backward country like North Korea.
So some other group may be claiming responsibility, but that’s not necessarily the end of the story. If private groups can commoditize online attacks, then North Korea can make them.
So it’s profoundly silly for Justin Amash to be playing pansycrat and calling for a humbler, meeker American online. We should no more bow to Kim Jong Un online, than Barack Obama should bow to foreign leaders in person. We need a national defense online, including NSA.
