The Washington Post says North Korea may suspend its cooperation with the members of the six-way nuclear talks in protest of international efforts to sanction Pyongyang for its rocket launch.

The paper quoted a Senate official as saying Monday that the North may also expel international nuclear inspectors and possibly start reassembling nuclear facilities that had been dismantled.

However, the official stressed that the international community should not overreact to the rocket launch because it would do no good to have the process of denuclearizing the Korean Peninsula set back due to a satellite launch attempt.
