I learned that all the other species the aliens have supposedly conquered must have been primitive races or they had the collective intellect of a amoeba, because judging by the aliens complete lack of any comprehension of strategy and tactics etc, only Neanderthals could lose a war against them - and even then maybe not.
The alien mother-ship is large and powerful enough to drill to the center of the earth and extract the core....but it can't take-out US Central Command.
-If you take out a ship that is massively smaller and less dangerous than the fleet you encountered 20 years ago, assume that you just took out the alien's entire retaliation effort and start planning your celebration. -African warlords are better at translating alien languages than the rest of the world that was able to reverse engineer alien technology. -USA military has no one over the age of 30. -The only realistic way for the aliens to lose is if they send out their queen, so they send out their queen to act as a foot soldier with minimal protection. -Next sequel will have a ship larger than the planet this time, and will have to figure out how to land Earth on it.
So typical of Americans. Shoot first (at your ally) then ask questions later. Must remember to all cheer like morons when you destroy it. Stupid Americans (again)
Only an Ex-President of the United States or his daughter can pilot a bomb into the alien command ship. Because there wouldn't be a nameless ESD pilot that no one ever heard of before that would, iunno, just volunteer.
When you need a skilled pilot to volunteer for a suicide mission to save the world, choose the guy who clearly hasn't piloted any plane in 20 years much less one of the advanced alien hybrid ones.
Make sure when you sign that permission slip for your kid to go on a field trip that it says "Teachers and chaperones are not to abandon students in the event of an alien invasion".
A school bus is like a cat teaser for giant alien queens: they just can't resist the bright color and movement!
When you are in a coma for 20 years, you must always be kept in the same location in which you fell into that coma.
When you are in a coma for 20 years, your high-maintenance and luxurious long locks will be maintained because hospitals have salon departments staffed with skilled hair care professionals.
After the massive death and destruction of the first alien invasion, 20 years is more than enough time to not only rebuild the earth's major cities and infrastructure but also establish a sophisticated moon base. Because world peace and alien technology are magic.
During an alien invasion, it's best to avoid pranking or jump-scaring your buddies after surviving a crash landing inside the alien mother ship. They might a) think you're an even bigger dick than you already were, and b) shoot you.
When visiting the moon base of the planet you know has survived an invasion by the aliens you've created a training base to defeat, don't have any shields against the weapons/technology you know that planet will likely have acquired from the aliens you've been training other species to fight.
