The US have ramped up efforts to take down the reclusive state and are rumoured to be carrying out “left of launch” attacks against the North’s missiles.
This means that Washington are deliberately allowing infected microchips and other components to be smuggled into the Communist state to be used for its weapon programme.
When the defective parts are fitted into weapons, the US is said to have the ability to veer them off course or destroy them completely.
Military capabilities have been put to the test recently by Japan, South Korea and China recently amid growing pressure of a nuclear war.
North Korean leader Kim Jong-un fired a ballistic missile over Japan earlier this week, causing alarm across the world.
A single bomb of this size is capable of wiping out a major city experts said.
Kim Jong-un ordered the nation’s sixth nuclear test as tension continue to escalate with the US.
According to North Korea’s state media the test was a “perfect success” and a “meaningful” step in completing the country’s nuclear weapons programme.
