North Korean doomsday weapon could kill up to 90% of Americans, experts warn experts, 10-17

US officials have been given a stark warning about the potential dangers of a nuclear electromagnetic pulse (EMP) bomb triggered by reclusive North Korea .

According to experts, such a blast could end up killing 90% of Americans indirectly by knocking out the power grid and all electrical devices within the blast radius.

Dr. William R. Graham and Dr. Peter Vincent Pry from the EMP Commission outlined to the US House of Representatives the dangers faced by a detonation - which is when a hydrogen bomb is detonated at an altitude of between 30 and 400km above a target. Such a weapon would knock out things like refrigeration for food storage, electrical lights and communication and water processing.

"With the development of small nuclear arsenals and long-range missiles by new, radical U.S. adversaries, beginning with North Korea, the threat of a nuclear EMP attack against the U.S. becomes one of the few ways that such a country could inflict devastating damage to the United States," the pair warned in a written statement .

"It is critical, therefore, that the U.S. national leadership address the EMP threat as a critical and existential issue, and give a high priority to assuring the leadership is engaged and the necessary steps are taken to protect the country from EMP."

Dr. Graham, a former science advisor to president Reagan and Dr. Pry, a former CIA officer, urged president Trump to prepare for a possible EMP strike.

They also warned that North Korea's weaponry is becoming more of an issue as the reclusive nation continues to schedule ICBM missile tests.

"The EMP Commission finds that even primitive, low-yield nuclear weapons are such a significant EMP threat that rogue states, like North Korea, or terrorists may well prefer using a nuclear weapon for EMP attack, instead of destroying a city."

The higher an EMP bomb is detonated, the wider the range of destruction.

At 400km (250 miles), an EMP bomb would be just under the orbit of the International Space Station and the resulting detonation would be enough to affect the majority of the US mainland.

North Korea 'could kill almost four million people in Seoul and Tokyo with retaliatory nuclear attack' 10-10

A US military assault on North Korea could prompt a last gasp retaliatory nuclear attack by Pyongyang on Seoul and Japan killing as many as 3.8 million people, according to a new analysis of the destructive potential of Kim Jong-un arsenal.

Donald Trump has repeatedly warned that all options remain on the table – including the use of force – in dealing with the North Korean threat.

However, analysts say the US is hamstrung by Pyongyang’s growing weapons stockpile and the fact that major population centres lie well within its range.

A detailed analysis by 38 North, a programme at the US-Korea Institute at Johns Hopkins School of Advanced International Studies, has crunched the numbers, based on North Korea’s likely arsenal of as many as 25 weapons with possible yields of up to 250 kilotons, of the sort tested last month.
Using population density figures and blast radius estimates, Michael Zaguruk, calculated that a single detonation over Seoul could kill almost 800,000 people and over Tokyo would kill almost 700,000.

Those numbers rise to a combined total of almost four million dead if North Korea manages to launch multiple rockets carrying its latest thermonuclear bomb.
And that is without considering the effects of radioactive fallout.

The numbers are a sobering reminder of the difficulties of dealing with Mr Kim and his nuclear arsenal.

Mr Zaguruk explains the possible measures available to the US and the possible response.
“This could include such options as attempting to shoot down the test missiles or possibly attacking North Korea’s missile testing, nuclear related sites, missile deployment areas or the Kim regime itself,” he writes.

“The North Korean leadership might perceive such an attack as an effort to remove the Kim family from power and, as a result, could retaliate with nuclear weapons as a last gasp reaction before annihilation.”

Meanwhile, North Korea continues to press ahead with its nuclear and missile programmes.
Fresh reports circulated on Friday that a long-range missile, capable of reaching the west coast of the US, was being prepared for testing.

Anton Morozov, a member of the Russian lower house of parliament's international affairs committee, made the claim after returning from a visit to North Korea.

"They are preparing for new tests of a long-range missile. They even gave us mathematical calculations that they believe prove that their missile can hit the west coast of the United States," he said, according to the RIA news agency.

"As far as we understand, they intend to launch one more long-range missile in the near future. And in general, their mood is rather belligerent."
