Just got an email from an old friend of mine who's still in uniform. He's a lt col now and he tells me that the Air Force is about to move into INFOCON 2 due to the threats by North Korea to "wipe out" the United States with computer viruses and nuclear missiles. Frankly, I'm not sure which is worse. The missiles might not hit their mark, but a devastating computer virus could destroy trillions of dollars of productivity all over the globe. My wife and daughter are really concerned that I'm here in South Korea where I might be killed. But I have to protect South Korea's critical network infrastructures. It's too important to leave our allies swinging in the wind. I wish everyone back at home a safe and non-infected July 4 holiday. Grill a brat for me!
