It does indeed sound very strange, but at least it doesn't immediately
appear to violate any basic law of physics (as opposed to some other
claims of "superweapons" ;-) ).

Every "superweapon" of 20th century violated basic laws of physics that were
prevailing before Dec 14,1900.
Next generation of superweapons will also surely violate basic laws of physics
that we learned in 20th century.
Orthodoxy in science was always a major problem.


The whole concept sounds a bit like a laser, except that the "decay"
happens in the nucleus and not the electron shell.

Thats correct,but much more interestingly you can achive similar interactions
if you place materia in a very intense EM field,which makes nuclear wepons very
dangerous to store anywhere if you your opponent has EM weapons capable of
recovering initial energy anywhere they want to.
BTW new physics is accepts the non locality and zero point energy which
apparently extremely well understood by pre 1945 German scientists.
Besides of Penrose and Zeilingers works you may also want to check out works of
Haisch,Puthoff and Rueda for more info.
