Tokyo: North Korea's botched missile test on Sunday may have been disrupted by a secretive US program of cyber and electronic warfare designed to sabotage launches.
Pyongyang spent the weekend showing off its arsenal of ballistic missiles alongside thousands of goose-stepping troops in a military parade.
But the regime suffered a humiliating setback when a test-launched medium-range missile exploded four to five seconds into its flight.
Under Barack Obama, the US stepped up electronic and cyber attacks on North Korea's missile programme.
Those efforts are reported to include hacking and the use of electromagnetic weapons capable of disrupting electronic equipment.
President Donald Trump's national security adviser promised further action to ensure North Korea was never able to threaten the US.
