Thanks for sharing that. Some interesting things I just read about it:
This "Star Wars" technology is carried on a 747.
The U.S. has been shooting down Katyusha rockets at the White Sands proving ground in New Mexico since 1998 using a high-energy laser weapon....
...it would still cost more to shoot Katyushas out of the sky than it costs the enemy to make them.
Consider also that a single nuclear warhead detonated high above the U.S...would create an EMP so large that it would fry most electronic circuits in the U.S.!
