korea's response might be and whether they were going to have to advise president obama to get involved. they were in constant touch with admiral robert willard head of the u.s. pacific command in hawaii and general walter sharp commander of u.s. forces in south korea. earlier, sharp had gone to the american ambassador to seoul kathleen stevens to the blue palace, the residence of south korean president lee myung-bak. though the u.s. declined comment, lee myung-bak's spokesman said, quote, the u.s. side said it supports south korea's military training plan irrespective of north korea's response and that it will stay with us whatever happens. sources tell cnn the u.s. did the not openly deploy any military assets wanting to stay as low profile as possible so as not to send any mistaken signals to the north. only this morning did it become clear north korea was not going to respond. >> joining us now on the phone from pyongyang in north korea we have wolf blitzer, invited to travel to north korea with bill richardson of new mexico and has had rare access into the hermit kingdom. thank you for joining us, wolf.
