Un investigation report submitted to the United States Congress points to the great vulnerability of the United States in the event of an attack using an electromagnetic pulse weapon, such as those currently being developed in China.
According to this report, an attack over the United States with a 300 kt nuclear weapon exploding between 40 and 400 km altitude would lead to the destruction of all of the country's technological infrastructure. According to projections, this would lead to the death of 90% of the population in less than a year. He specifies that even the country's nuclear response capabilities could be largely compromised by this single attack. On the other hand, the report estimates that Europe would be more resistant to this type of attack.
China is developing a high-power electromagnetic pulse weapon, multiplying by 4 the energy deployed at equal power. According to the report, Russia, Iran and North Korea may also have similar programs.
