In addition to all of our wars in the Middle East and the war that has erupted on the streets of America, we are now engaged in a cyber war with North Korea and an economic war with Russia.  Without a doubt, the United States has the capability to do a tremendous amount of damage to both of them. But what about the damage that they could potentially do to us?  We have a society that is absolutely teeming with soft targets.  Our internet infrastructure is extremely vulnerable, our debt-based economic system is already teetering on the edge of disaster, and government officials freely admit that security at key facilities such as power plants is sorely lacking.  And these kinds of bitter conflicts have a way of escalating.  The North Koreans and the Russians are both very proud, and neither one is going to back down any time soon.  If a foreign power wanted to really make us hurt, it wouldn't take much imagination at all. There are thousands of ways to do it.  So Americans should not just smugly assume that we are untouchable.  In a war, it is often those that are overconfident that get hurt the worst.

Last week, Barack Obama blamed North Korea for the nightmarish hack attack on Sony Pictures Entertainment and he promised that the U.S. would respond.

Well, it looks like that response began on Monday. According to Bloomberg, North Korea's connection to the Internet was totally cut off…

North Korea's limited access to the Internet has been cut off, according to a network-monitoring company, days after the U.S. government accused the country of hacking into Sony Corp. (6758)'s files.

North Korea, which has four official networks connecting the country to the Internet — all of which route through China — began experiencing intermittent problems yesterday and today went completely dark, according to Doug Madory, director of Internet analysis at Dyn Research in Hanover, New Hampshire.

Needless to say, that got the attention of the North Koreans.

On their end, the North Koreans are still denying that they had anything to do with the attack on Sony. And we may never know the actual truth.  In reality, Russia could have carried out such an attack.  Or it could have been the Chinese. Or it could have even been a false flag cyberattack conducted by a three letter U.S. agency. We just don't know.
