Humans will return to Pandora as long as they need Unobtainium. They will have a larger and better army. The Na'vi will be prepared. They will clash once again and one has to win the battle. Who will win the war. Humans or Na'vi? The Na'vi would be using guerilla tactics again. The humans will use deforesting tactics. They also won't leave their base unprotected again just as the first time. That's why the Na'vi conquered the humans. The humans had lost almost all of their army and their base was unprotected. By the way it's far easier to hold a position instead of taking over a position. The humans will use Napalm, AA-fire etc. And the Na'vi will ask alot of clans to join the war. They will outnumber us, but can they also win this war?
