as tin foil as it sounds, i've seen some pretty impressive and scary tech that means no world leader is safe.
I think the only reason the shadows dont kill their opponents is the status quo, there would be to many questions.

I would say more that the folks that can make it strongly suspect we have it, but it hasn't been really used somewhere the world would see it. The Chinese are meandering along the right path, but aren't there yet. Maybe a demo would give them more of an idea on what we've been doing right and what they've been doing wrong. You've got to wonder what's going to happen when someone else gets REALLY close. If I were to advocate a first strike, that might be the only scenario. How do you defend against a basically indefensible weapon...by hitting first.
A metamaterial is an artificial material that manipulates waves like light and sound through properties of its structure rather than its chemistry. Researchers can design these materials to have rare or unnatural properties, like the ability to absorb specific ranges of the electromagnetic spectrum or to bend light backward.
"These materials are made up of a grid of separate units that can be individually tuned," said Willie Padilla, professor of electrical and computer engineering at Duke. "As a wave passes through the surface, the metamaterial can control the amplitude and phase at each location in the grid, which allows us to manipulate the wave in a lot of different ways."
In the new technology, each grid location contains a tiny silicon cylinder just 50 microns tall and 120 microns wide, with the cylinders spaced 170 microns apart from one another. While silicon is not normally a conductive material, the researchers bombard the cylinders with a specific frequency of light in a process called photodoping. This imbues the typically insulating material with metallic properties by exciting electrons on the cylinders' surfaces.
These newly freed electrons cause the cylinders to interact with electromagnetic waves passing through them. The size of the cylinders dictates what frequencies of light they can interact with, while the angle of the photodoping affects how they manipulate the electromagnetic waves. By purposefully engineering these details, the metamaterial can control electromagnetic waves in many different ways.

I wonder if this would apply to optics, you could correct for atmoaphearic disturbances right on the lense, or make better mirrors for microscopes, some a kin to a perfect mirror

or ways to thwart optical tracking Russian missiles.
Wonder woman and invisible girl would be proud.
