The technology today is so advanced that each country has the technology in their arsenal, especially the super powers. The United States has the largest amount of EMP weapons (we refer to them as directed energy weapons, linked to the SDI/Strategic Defense Initiative/Star Wars program).
The first poster in this thread called it fear mongering, but if any country decided to attack us with one of these weapons, they'd be able to do some damage just like the original article says.
An issue is also not the politics because experts have been going over the mystery of directed energy for decades. In the United States, the whole directed energy issue is "classified" and more secretive than the Manhattan project (which was the project that developed the first nuclear bomb, which was pretty secretive).
What many Americans don't know is the government knows all about directed energy but they don't want the public to know about it because of all the experiments and crime that have occurred with it. There's like a big case of many with knowledge of directed energy getting assassinated, and the issue of the public being targeted with weapons attacks and torture with it. Senator Paul Wellstone was assassinated in 2003 with it, the World Trade Center was dustified with it in 2001, thousands of people report being mind controlled and experimented on with it (or otherwise being murdered/hurt with it).
The Strategic Defense Initiative is already out there and the EMP weapons are deployed globally. In all satellites, phased array antenna, and radar systems. There are literal "goldeneye" weapons capable of targeting both humans and machine alike all over the world. But let me give you a hint about SDI and Star Wars: It can both injure people, and protect them. In fact they can create a shield of electromagnetic energy around any town or city, or even an entire country to fully protect the area from EMP and nuclear blasts (in fact, I suspect the United States to be shielding itself to protect itself from psychic warfare and remote eavesdropping from other countries using this technology, to for one thing, prevent other countries from getting access to at least our top officials and generals brainwaves and thoughts in secret).
However, the question is, will the government use the SDI weapons system to protect Americans, or only themselves? Therefore it is worth worrying about why there are no EMP/EMF weapons shelters for humans, and all our equipment is unshielded and unprotected, because we truly can't trust our government if they're going around committing crimes with these weapons systems and keeping the whole program pretty much locked down and secretive.
Learn more by researching Dr. Robert Duncan (DOD/CIA/US DOJ physics, and weapons/surveillance system architect). Watch the episodes of Jesse Ventura "Conspiracy Theory" titled Brain Invaders and Death Ray. In fact I have both of those on my website and more details about these weapons on this page of my website: http://www.oregonstatehospital...
They truly do have an EMP type directed energy weapon currently pointed at every man women and childs bodies and brains right now, just holding back the command to kill.
