Is the Korean War about to Re - Start in 2009 ?

BBC News: Reports that North Korea has nullified the truce that ended the Korean War in 1953, it will take action if South Korea stops its ships to prevent the selling of illegal technology. One has to ask what game North Korea is playing, it cant want a War with the United States, it will lose, the regime would fall and China would have a big mess on its hands. One can postulate that these actions by North Korea is due to an internal struggle for power, it seems the succession has become an issue, thus we could have different sides showing who has the backbone to take on the USA and South Korea. The problem for the Obama Administration and the West is that North Korea is a very closed society, thus getting any real information on the issue is hard, thus what does President Obama do about North Korea. If talks are off and if the USA and South Korea starts to blockade North Korea then the North might take action, thus a very tricky situation. One could start a blockade outside the waters of North Korea in international waters and then check the ships but the North might attack anyway, but the USA cant allow North Korea to sell technology to Iran either, Israel will attack Iran if its go nuclear. Will be interesting to see what the UN and Obama does about North Korea, appeasement will be seen as a green light to Iran to go nuclear but military action is out of the question, North Korea is a nuclear power. I wish we had full working SDI, or Star Wars, then we could take care of North Korea, Reagan as always was right.
