So I was sharing this with [@Gowi] but I want to toss this out there for everyone so that's its clear, coherent and everyone has an opportunity to chime in or shape it.

It would be difficult to tell a Green Lantern story without some conceptual understanding of galactic politics. In a universe where the Shi'ar, the Green Lanterns, the Nova Corps, and the Brood (as well as the Guardians and the Watchers) all occupy the same space, I need some idea of what the relationships between all those competing interests are, especially as DC's Green Lantern Corps and Marvel's Nova Corps are basically the same thing.

At the same time, I don't want to lock someone out from coming in and dropping a sweet as Sam Alexander application. So, here's the rough framework I came up with as I started sketching out Kai-ro's story and the galaxy it takes place in. Feel free to smack me if this is cracked out to all hell.

A United Nations parallel, known colloquially as [b]the Coalition[/b]; referring to those governments that are signatory to the Galactic Coalition in Partnership for Peace Treaty signed at some point after Krypton's destruction on Oa (hence referred to as a document as the [b]Oa Accords[/b]). My rationale is that the history of war between the Xandar and the Kree, coupled with the galactic superpowers doing nothing to stop the destruction of Krypton (not to mention the existence of existential threats such as Galactus...) would prompt some political action to promote cooperation.

Members of the treaty agree to mediation and alternative dispute resolution measures to resolve points of contention between interstellar powers, with contributions toward peacekeeping forces. Made up of dozens of worlds, it is led by the Security Council with its five permanent members.

1. The Maltusians (Guardians of the Galaxy). They operate the Green Lantern Corps, providing enforcement of interstellar domestic law and operating the felony level courts of interstellar law.

2. The Watchers. They serve as observers and recorders of history, though some more actively support the Green Lantern Corps as dispatchers or "early warning system" for threats such as Galactus, etc.

3. Xandar. Represented by Nova-Prime, they contribute the bulk of the military forces to the Coalition in the form of the Nova Corps.

4. Kree. Represented by Ronan the Accuser, they contribute minor forces to the Coalition and serve primarily as a "check" against the Xandar, with whom they had previously been at war with.

5. Currently vacant, formerly occupied by Asgard (which has since withdrawn from the Oa Accords)

The lack of 5 members means that in recent years, the Coalition has been completely non-functional. The Guardians and the Watchers abstain from voting, while the Xandar and the Kree cannot agree on the color of the sky. The Kymellian Technomancy and the Tamarans have each been nominated to replace the Asgardians, but each nomination has become embroiled in political posturing and protests by the Z'ynx and the Daxamites who feel underrepresented.

[color=lime]tl;dr[/color] the Green Lanterns are space cops, the Nova Corps are UN peacekeeping forces from Xandar. And the government is currently completely ineffective.
