The head of the ruling party in Japan has said that because the Kim Jong Il regime has not been sincere/trustworthy in negotiations that regime change may be the only option.
This makes sense. Only how? I think an invasion by China makes the most sense. We should let them occupy North Korea and let them set up a new regime.
ALSO: here's a link to an article from a South Korean newspaper with photographic PROOF that billboards of KIM JONG IL are coming down all over North Korea.
