To plan against an enemy you must surely have an idea of their capabilities, we know of no alien races so unfortunately there is no way we could plan against an attack by them. Possibly an exercise to test officer cadets imagination or something similiar??

Well nukes would be about the only option really.
If aliens came to attack Earth, it would mean that they would be technologically more advanced than us (the fact that they have travelled so far thru space...) and would likely possess more advanced weapons. Shields (of the startrek/starwars/stargate/ sci show variety) or no shields a nuke blast nearby would be bound to cause significant damage.
There would be very little reason for aliens to come all the way to Earth simply to destroy us... If they were hostile, it would either be they come here to colonise, or to enslave us, simply destroying the plannet would serve very little purpose...

Maybe they have a time machine that has allowed them to look into the future and see a time where Earthlings are giving them trouble.
Or maybe they would come through to build that interstellar superhighway.
I think sci-fi writers have come up with numerous excuses for aliens to come Earth to destroy us.

You can also argue that even if time travel is impossible, as conventional thinking still tends to assert, then the lack of intervention in our present, to say nothing of our past, is no guarantee that at some future time (perhaps literally tomorrow), some rogue members of an alien civilization will view Earth as fair game from close range. And since such members might be their equivalent of motorcycle rebels, raisin' hell for the sake of it, well, there goes the argument that a sufficiently advanced race wouldn't take advantage of an immature one such as ours.
The argument that a race sufficiently advanced to travel interstellar distances wouldn't have a chance of being defeated is better, but there's no saying whether the above argument might still apply. For example, on Earth today, the existence of high-tech militaries is not absolute assurance that mercenaries wouldn't want to try their hand at doing small-scale operations that don't require anything more advanced than Rugers or AK-47's.
Hence, if some interstellar equivalent of the bad guys in those Mad Max movies comes along, we -- meaning humanity -- might still have a chance of holding them off, at least until the interstellar cavalry comes along. If it ever does.
