The fact that the RDA have a completely unopposable beachhead (i.e. low Pandoran orbit) makes the whole thing strategically even easier.

Considering the effect of Moore's Law, the apparent wealth of the RDA (unimaginably vast), and the technology already available/demonstrated, IMO, it's unbelievable for the Na'vi to win. If the RDA decided to colonize again in, say, 10 or 20 years time, there'd be very little the Na'vi could do about it.

(And yes, of course I'm sticking to conventional weaponry and low tech. )

You're still not sticking to canon. Going "hurr durr invade use spess mehrens" just marks you out as a troll.

Aurora is right, but I would add that even that is going to be impossible because they are limited by what an ISV can actually bring there.
