Earth is invaded, then we win.

[dvd_72]

Well if in their culture it is alright to enslave "lesser species" perhaps the argument could be made that, because we have broken their hold over us, we are no longer quite as "lesser"?

Probably stick them in holding camps as we prepare ourselves. Not death camps or anything, just a place where they can be kept alive but monitored until we decide what to do with them once and for all. I'm going to assume that the aliens didn't pack up all of their tech or anything, so we have access to it. We could use that tech to help shore up our defences until the aliens do return, at which point we negotiate the return of their colonists in return for them leaving us alone.

I mean, retaking an entire planet must gain some kind of respect from the greater galactic community right?

 

[Old Father Eternity]

Ok. Optimal outcome. Assuming they did not do a complete wipe out of our intellectual and tactical minds and that their main fleet is not present, we should theoretically be able to infiltrate, sabotage and employ industrial and political espionage and eventually overthrow their rule. Whatever was left of their population should be allowed to stay and assimilate however notified that if they make a false move they will be made an example. We should then proceed to learn even more about them,in-depth study (by peaceful means) of social and political order, biology, technology, military tactics. All that assuming their FTL drives are not advanced enough to make the journey in less than...say five years. Then open up comm-channels, set our conditions for at least neutral co-existence. Should they fail to comply, we will make clear that when given the chance (which we have had) we are a military force to be reckoned with. Then proceed to decimate their forces but leaving the civilization as intact as possible.


However, knowing what us humans are like, we will most likely get all the knowledge by force and proceed with remorseless annihilation.


Worst possible scenario, as some have pointed out, orbital bombardment, persecutions on surface after uprising attempts and eventual extinction of our species

 

[BlackEagle95]

I say just shove them somewhere and keep a downright oppressive eye on them. Replicate their technology, and hopefully take to the stars and look for Allies against the offending race/alliance. In my ideal situation, the two coalitions wouldn't go to war, but agree that humanity has earned a place in the galaxy. The surviving aliens would be sent back, and our relationship with our former oppressors would be cold if we have any further contact at all.

If we can't find any other races, then I fear we might end up going Ender's Game on them (Maybe not to that extent, but there would have to be retaliation). Can't really say how the real world would react to that in the long run, but if they are persistent, then it might be our only choice. I guess the survivors would have to go as well.
Unless of course they accept defeat.

I just really don't want an interstellar war. My idea's rely on the shock of defeat, but that may be enough.

 

[Toaster Hunter]

Press them into service to create their technology. Execute all who resist. The survival of the human species is at stake, so we can't afford to be nice

 

[LoneWanderer19]

Easy.

First we build these massive underground bunkers, move all the survivors in them, drop nuclear bombs everywhere, then after the bunker overseer gives the all clear, we use a terraforming device to clear all of the radiation out and reform the land!

 

[Guffe]

I'd probably be one of the ones dying when they invade.
There went my saying in anything about the future...

 

[spartan231490]

Execution. It's the only way to be sure that they won't call for reinforcements.

 

[SFMB]

Exile. First just confiscate all the alien-tech, put them in some rockets and thank them for culling the mankind. Then just push the button and off they go. Or if you really want to get rid of them after the "Humane-you-cannot-drop-to-the-aliens-level"-morons are glad of your "humane" way of sending them home, the rockets hit the Sun.

 

[Marcus Kehoe]

Something very similar to what we did to Germany, disarm them and separate them. Show them peace and learn what we can form them. Of course kill any we know committed genocide or killed innocent's.

 

[lacktheknack]

I don't think we would win against an army of aliens that has mastered interstellar travel before we do.

They'd have us beat intellectually and technologically. We'd only stand a chance if somehow our atmosphere was making them less intelligent with each passing day.

We're more technologically and intellectually advanced than saber-tooth tigers, too, but if was a colonization force of, say, a few hundred thousand humans against several billion angry saber-tooth tigers hell-bent on stopping the colonization, guess who will win. (Hint: not us.) Plus, the technological gap is probably smaller than that.

Anyways, major containment facilities would pop up to hold them, they'll be useful when the inevitable bargaining table arrives.

 

[Stravant]

District 9

Enough said.

 

[Jetpack Stu]

force the cooperation of the hostage aliens to reverse engineer us a nice floatilla and get the hell out of dodge ASAP using the scorched-earth/hide in bunkers policy for the remaining human population left behind and return every 100 years or so to keep tabs on our planet and get new boats into the abyss, setting up colonies as we explore space until our empire is big enough to strike back without mercy.

 

[Marcus Kehoe]

Yeah,do what we did in Germany,because that ended well.

The second time not the first.

 

[GeneralFungi]

It's always funny to me when people talk of aliens, and regard them as some sort of perfect technologically based civilization. We put a ridiculous amount of money into fueling our armies and building powerful weaponry. Even if they mastered space travel, they may not have had the same advancements in weapons or other such things.

Someday we might even be the guys invading planets and enslaving alien races..

 

[Chevalier noir]

Forgive all of them them, grant them safe living on earth in exchange for a combination of our knowledge and theirs, teach them that we think imperialism is fundementally wrong and in a couple of decades, bounce out to space together!

I agree. Bury the hatchet, if they aren't a threat to us anymore there is no good reason to cause any more suffering for either side.

Why wouldn't we win?

All you would need to stop any army of sabertooth tigers is an aircraft and bombs, and that's just one 'hard counter' method. Have the military base housing the aircraft surrounded in electrical fencing, there's nothing they could do.

I'm sorry, but we can't even send Humans to Mars. If you think a force that could travel to other star systems wouldn't have us beat on every front, you're not a very bright person.

 

[GigaHz]

Incorrect. They may be able to master interstellar transportation but that doesn't mean they're invulnerable to our weapons. Hell, most likely, they won't even be armored against kinetic weapons, their society having moved onto directed energy instead.


All else fails we can just grab a crowbar.

Alright.

Swords and crossbows hurt right? How about you can have an army of say, 100,000 people.

You can go against my army of 20,000 people, with all of today's modern technology. This may include nukes, remote weapons, robots, and whatever else our modern army is capable of.

Tell me with a straight face, if betting on the correct army meant sparing your life, which army would you bet on?

But they're coming to us.

The colonizers wouldn't have the army backing them at the time (according to the OP), and bombing the area wrecks the point of colonization.

We don't HAVE to go to Mars, we just need to fend off an opposing interstellar army. And if you think that humans don't the the drive, ingenuity, and resourcefulness to do some major damage, you underestimate us greatly.

Besides, as someone else pointed out, the initial waves would be tempered immensely by them catching smallpox/polio/a good cold and dying horribly.

 

[Knight Captain Kerr]

I say grant amnesty in exchange for knowledge and disarmament. Then intigrate them into society as equals. Just because they aren't humans doesn't mean they aren't people. Hopefully we can put the differences our spiecies have behind us to build a better universe for all people.

However as much as I hate to say it genocide and concentration camps is probably what would happen.

I'm not a huge Half Life fan to begin with.

Maybe it was a bad example, but in the conclusions your drawing both waring factions are human. Obviously a Human vs. Human fight is going to come off relatively even, especially if the technology gap isn't too wide. A gap of 50 or so years isn't too much. But these are entirely different species and a technological gap of probably several thousand years, at least. You'd think that if they were smart enough to master interstellar travel and create such advanced weapons and technology, they would have more than effective tactics to handle any guerrilla approach we'd have. Who knows? Each alien may have thick armour, preventing even the most piercing and high calibre bullets through. Their energy shields might nullify any explosive through pulse waves. I really don't have any concrete evidence to back any of these assumptions up. No one does.

All I'm saying is, if I betting on the winning horse meant keeping my life, I'd bet on the aliens. Unless this fight were to take place in a few thousand years when our technology would be approaching parity, if not just a touch out dated.
