You'll probably find more solid examples by looking at history, like priests melting wax ships to destroy enemy fleets via image magic, people creating horoscopes of a king to plain their death, or seers advising leaders before wars. I suppose the sinuous, secret ways magic takes gives it no room in the modern world where you can launch missiles with a push of a button, a far more stable ritual than pricking dolls. Anyone high level enough to be calling shots is enmeshed in a political machine that can easily carry out its functions posthumously, or make it inefficient to rely on addling their brains because of the vast bodies that guide every action.
Well, usually, anyway. Back when a single broadcast of Fox and Friends couldn't radically determine a president's executive actions.
It's interesting to think of a world that's outpaced magic. In most every other sector, being a learned magician can still derive some benefit, but it's hard to figure where sorcery could fit in the context of modern warfare. I wonder if one day there won't be any magicians left at all.
