I'm not wearing tinfoil and I can think of reasons to keep anything of this nature under wraps from a national security standpoint. The best is that you want your opponent to know enough about what you got to deter them from aggression. If deterence fails, you want to have enough in your back pocket to obliterate them. If such a fallback measure depended on something wild like this, you wouldn't want you oppenents to know it is possible beforehand - such knowledge would allow them to duplicate or negate your advantage.
It's not that kinda thing.
To get any real advantage from it, we would have to do enough development and mass production to use it as the energy source in all our weapons systems and vehicles, which means completely redesigning all of them.
Releasing it would leave the middle East bankrupt, but it would just increase the profit of the energy companies.
Electrical companies are in the distribution business, not the power production business.
Fossil Fuel companies would love to concentrate on the petrochemical industry with ultra cheap energy and feedstocks.
The economy goes up and down as the reciprocal of energy prices. A radical cut in energy prices would set off a boom that is almost beyond conception.
That is how you would use a breakthrough like this to defeat any enemy.
