US President Donald Trump inherited a secret program, ordered by his predecessor, Barack Obama, of sabotage the North Korean ballistic missile program by cyberattacks.

Obama started the fight three years ago

Three years ago, President Barack Obama asked the Pentagon to intensify the cyber and electronic attacks against the ballistic missile program of North Korea with the hope that the launch ramps will be sabotaged when they will open. The result was that many missiles launched by the North Korean army began to explode, to deviate from the path, to disintegrate after launch or to collapse into the sea.

The proponents of these efforts argue that the punctual attacks have given a new dimension to the US missile defense systems, delaying a few years the capacity of the Stalinist regime in Pyongyang to threaten American cities with nuclear bombs with intercontinental missiles.

Other experts have become increasingly skeptical about Washington's new approach, arguing that the manufacturing errors, the opponents infiltrators and the incompetence can be factors that led to ballistics failed.

Kim Jong-Un, the North Korean leader, now claims that his country is "in the final stages of preparation" of an inaugural test with intercontinental missile.

Donald Trump will respond aggressively to threats

Donald Trump has drawn attention on several occasions that he will respond aggressively to the threats of North Korea.

The new US president could order to intensify the cyber and electronic attacks, but the efficiency isn`t guaranteed. He could start negotiations with Pyongyang to halt nuclear and ballistic missile programs, but the threat is likely to persist. He could prepare punctual bombardments on launch ramps, an option considered by Barack Obama too, but the chances that all the targets to be destroyed are really small.

He could make pressure on China to limit the support and the commercial relations, but Beijing never took steps leading to the collapse of the North Korean regime.

In the course of some recent meetings, the American presidential advisers to national security analyzed these options, and the possibility of resubmitting nuclear bombs in South Korea, as a warning.
