You know in Islam we believe that the anti-christ (dajjal) when he appears, he will have the ability to give people disease like they've never seen... and at the same time if people accept him in return cure them.
The other thing he will also have power over will be weather, where he will bring droughts or sever weather conditions and be able to bring rain to dried areas or avert bad weather if people accept him.
I can see how the world is heading in these directions.
Haarp can be used to send waves which can bring alive certain viruses not just control weather which can sit dormant for a hundred years even but with a certain frequency be activated.
Certain frequencies can cause physical harm, can alter the brain, induce sickness, cause cancer of course, cause panic, anxiety, depression, anger, amongst other things.
