The North Korean deadlock might come to an early end, if the US is able to start the direct talks with North Korea. The North Korea military regime went into a confrontation mode few months back and it pulled back from the multi national discussion forum unilaterally.
Also it went ahead with many long range and medium range missile tests, apart from many nuclear tests. The North Korean regime few weeks back indicated that it is ready for direct talks with US, and now US seems to be readying itself for the same.
