We might, Shimrod...

And we might not. I think we'll find out about that fairly soon.

"As if we wouldn't turn up next month with more and bigger weapons ..."

Yes, D. McG. That was the first thought that occurred to me at the end of Avatar. "Those corporate bastards will be back soon, and they'll bring more firepower." Pretty much a guarantee, I'd say. The Na'avi would have one big thing on their side next time though...that forewarned is forearmed. I think the mining company would find it very hard to start up any new effort there if they found the whole planetary society ready and waiting to exterminate them the moment they touched down. The Na'avi could well hold the Earthlings off forever if they were prepared to resist in that fashion....and it would prove far too costly for the Company to mount such long range missions in the face of such ruthless resistance.

That would be the only way possible to stop a successful takeover by the invaders.

North American Indians could have accomplished the same thing against the early White incursions provided they had been united in a common effort instead of divided against each other.

Given that the Na'avi in the film had decided to unite in a single alliance to defend their world, I think their defense might have proven unbeatable, if handled with enough determination, speed, and good planning. The benefit of having a few transformed Earthlings in their own ranks would have been absolutely crucial to that defense, giving them the knowledge of how to combat a technologically equipped enemy.

One more thought. Sometimes violence IS the only solution. It depends upon the nature of the conflict. The only way the English could possibly have been ejected from France at the end of the Hundred Years War, for example, was by violence. They had to be militarily defeated to get them to leave. Thus, Joan of Arc dictated many letters to the English commanders and King requesting that they leave France peacefully with the condition that if they did not, they would be driven out at the point of the lance and sword. They laughed at those requests. So they were driven out at the point of the lance and sword, just as she had warned them.

There are some cases where only the lance and the sword will settle the matter. It depends on whether you're dealing with people who are receptive to reason...or people who are not.

As the situation stood in the film, only violence was going to end that invasion of the Na'avi's world. No other way was even remotely possible. No apology needs to made for using violence in such a case. This is something all animals know and understand, and you can't make them feel guilty about it...
