premise: The U.S. State Department said Thursday that the United States is working to dissuade North Korea from going ahead with its plan to launch a satellite next month. U.S. officials say the launch is a disguised long-range missile test and would be destabilizing. State Department officials give no credence to the notion that the launch would be for scientific purposes and they say the United States is working diplomatically to try to prevent a North Korean action that they say would be provocative, destabilizing and unhelpful.
hypothesis: The U.S. fears that the North Korean satellite is a ruse to hide the testing of a missile.
