Iran is steadily working on a device to use to destroy the United States. More importantly, the weapon systems the Iranians are fast developing could be used successfully to destroy the US.
An Electromagnetic Pulse weapon deployed properly could destroy almost all the infrastructure of the United States leaving the population in the lurch trying to survive. This is achievable with the current weapons already developed by North Korea.
According to guest experts on Coast-to-Coast AM Talk Radio, three nuclear devices detonated 200 miles above the earth above the atmosphere strategically placed could destroy the entire infrastructure upon which we depend for almost all functions in the US. The small nuclear warheads already tested by North Korea would suffice to power an electromagnetic pulse strong enough to fry every solid state device in North America.
Currently, the Iranians are testing launching ballistic missiles from floating barge platforms. Iran is launching the missiles straight up showing little to no concern for either reentry or targeting systems to hit land targets, neither of which is required for the deployment of an EMP weapon.
There is only one anti-missile facility in the entire US, known publicly. The meager facility in California is nothing more than a mere development & testing facility. However, Alaska is partially covered by an anti-missile defense system. This may be because the United State’s biggest and most significant and most secret weapon resides in Alaska on several acres, HAARP.
