This is a powerful statement by the US in terms of its commitment to South Korea. However, North Korea’s pattern seems to be to provoke once the last provocation has died down, as in their estimation the Western mind set cannot focus for more than a few news cycles. North Korea sunk the Chon An and killed 40 plus South Korean navy personnel, Then after a while, a South Korean aircraft went missing and 2 Air-force people aboard. I have no idea what happened to them I didn’t follow that story after the disappearance.
Then the recent attack on the ‘Disputed’ yet clearly South Korean Island. My guess is, the USS George Washington will sail around the area for 3 weeks while the North prepares it’s next outrage and once the ship has left they will commit it. North Korea may be evil, may not care one bit about the safety or well being of its own people and may be prepared to see some or all of them die in pointless provocations, but they are not stupid.
