<---was in the military once.
Anyways, in a militaristic viewpoint being able to harness such power is dangerous. Many of the military are devoted to training and with time they can become a very lethal weapon themselves with or without jutsu.
It would be interesting but if it became an exclusive thing many people would try to get in just to learn especially terrorists.
The amount of destruction that can happen is probably not as damaging as an atomic bomb but still devastating nonetheless. Imagine people doing these wide area techs in a war? Not to mention it would take years to train people who could be as good as the ones in Naruto. You won't see OP 16 year olds in the battlefield (at least on the US side).
I wonder how that would even work? Many religious groups would think jutsus are the devils magic or whatever nonsense they can come up with. I would like to see how they justify that! xd
