[Guardians of the Galaxy] Why does Nova not have any planatary defense?

Wondering. Even our earth could send a few nukes to oblitarate that ship and Nova, who just came out of a war, has no planetary defense and only a few shitty small ships to stop invaders?

At the time of the attack, the entire Xandar Navy was away, presumably defending worlds closer to the Kree/Xandar border. They didn't expect that a rogue zealot would attempt to raze the planet, and so what if he did? It's not like he'd be able to do much damage by himself without some kind of extraordinary deus ex machina superpower artifact, right?
