The North Korean rocket was shot down down by the US as a test for their new star wars defense system.
The fuel tanks were targeted shortly after take off by a directed energy weapon that heated the fuel tank, and caused an explosion.
This was done covertly, and made to look like a failed launch.
North Korea are also investigating potential sabotage that could have occurred on the ground by "foreign agents"
These covert missions are becoming more and more common by ally intelligence agencies (MI5, CIA, Mossad) because it is hard to prove who carried out
They can deny involvement - blame some one else, and claim to be the victim if their targets retaliate.
