Creating the holograms is simple - the UFP has been manufacturing mobile emitters since day one. They just don't happen to be teeny weeny badges that a humanoid hologram can wear on his chest. But we've seen tabletop models and rooftop models in addition to large starshipboard mounts.
Why? Nobody has come up with a "counter tactic" yet that would negate the usefulness of nuclear missiles, even though those are just as gimmicky a technology as holograms, and just as full of "weaknesses". Nor is there a "counter tactic" to the use of biological or chemical weapons that would negate their usefulness. Not even in the Star Trek universe, where it might be dramatically customary for McCoy to rummage through his black bag for two minutes and come up with a potion that completely negates a disease or a poison, yet for some strange reason diseases and poisons still serve as efficient killers.
It's probably far easier to come up with a counter tactic that completely negates the advantage of having live human(oid)s on the battlefield...
And why would that be in any way specific to holograms? All warfare is just a waste of energy, and destructive to the territory that you want to possess. Especially if you fight a long and drawn-out war with clubs and stones.

Once they've learned what you've been doing with the holographic emitters, they would be practically useless. Anybody could probably come up with a counter tactic.

Then both sides realise that it's just a waste of energy, and destructive to the territory that you want to possess.
