Josh Marshall has an excellent analysis of the seriousness of the recent escalation of the North Korean situation. Meanwhile, John Robb is contemplating the consequences that could spin out if the North decided to take advantage of our focus on Iraq by making a grab for South Korea.
In that scenario, all hell breaks loose because the US doesn’t have the troops to fight both wars at the same time. In that situation it is likely the US will use force multipliers like tactical nukes to emasculate North Korea’s military.
Very thought-provoking stuff (if by thought-provoking you mean terrifying).
