Could we actually fight a war against an alien race?

Why? I like to compare technology to developing for a console. Sooner or latter you are going to hit an obvious physical limit. What if guns are indeed the best way to kill someone, that neat carbon nanotube fiber never overthrows steel, antimatter drivers are too expensive even for interestelar travel?

Hell, think of the ammount of stuff that has been "30 years into the future" since 1950. Even sci-fi seems more aware of what is and what isn't possible for us. Notice how Avatar and Mass Effect seem much closer to us, even Crysis 2 in a way, since this thread is more about it.

Compare to the american colonization if it's worth anything. Europeans were two thousand years ahead of most native american people and still had lots of reasons to fear them. If it wasn't for smallpox colonization probably would never have happened.

And all of that assuming there's a more advanced civilization somewhere within our reach and they intend to conquer us for whatever reason. Life is probably fantastically unlikely and nothing guarantees us that another sentient species would have our needs, chance, dumb luck and psychological profile to develop a high-tech civilization. For all we know there could be six Na'vi planets around the galaxy and that's it.

I think we are much further from being able to travel to other stars than when Europe fought against Native Americans. It's like if we sent the US army now to deal with native Americans.

If they can come here then they can launch a million nukes on us from, say, the moon and there's absolutely nothing you can do against that.
