DARPA Neurologist and Chief of the Neuroethics Studies Program at Georgetown University, Washington DC, Dr. James Giordano, who is also a weapons expert, started his presentation at West Point NY Military Academy by saying, "The brain is and will be the 21st Century battlefield. End of story." 

DARPA stands for Defense Advanced Research Projects Agency, a Pentagon thinktank.

Dr. Giordano talks about how Directed Energy can be and is being weaponized. Individuals' brains can be targeted by microwaves, the type of 5G and soon to come 6G, of which you see antennas growing like mushrooms all over the word.
