Cyberfederation
Two years into what the homeline calls the four years war a group of Starfleet officers and corporate magnates launched a coup against the "incompitant cowards on the council who have led us to the brink of defeat."
What no one knew was that the Klingons were stretched to the limit and ready to snap, which is what happened in the home line.
Here a brief civil war gave the Klingons time to regroup and the war became known in this universe as the eight years war.
The Vulcans tried to withdraw from the Federation but the Human and Andorian coup leaders ordered their loyal forces to destroy Vulcan, thus showing the price of defiance. The destruction of Vulcan caused a number of ships to go renegade but after a brief struggle the Revolutionaries had seized power.
This leads to a gov't slightly behind in tech level but more focused on military preparedness and patrol of "member" worlds.
Political prisoners are forcably turned into cyborg killing machines controlled through mind control chips and rebel groups strike at the forces of the evil Federation.
I used this universe as the basis for a campaign once and the players enjoyed the differences to a normal campaign.

There are few problems in the galaxy which cannot be solved by a suitable application of concentrated phaser fire.
