Why is everyone worried about North Korea? They can really launch anything and if their rocket does knock out some computers-we would vaporize North Korea with rockets from a submarine or even an old B-52, Even Obama would be forced to act if we are attacked. The N Koreans are just trying to get some bail out money. Nothing to worry about.
Remember during the campaign when Biden said (I paraphrase) "0bama will be tested early; his response may not seem the right thing to do - be patient with us"?
We are not willing to have Americans killed to remove all doubt.
Only Obama is willing to have Americans killed, Americans attacked because he is not defending America, he is destroying America.
