Yes, I agree. There would almost certainly be a bit more of a militization of the world cultures because of fear of possible attack or subjugation.
Space would finally become weaponised(at least openly, it's already militarized). I do wonder if there is thought put to trying out a world
government how well the various countries can work together?
Hopefully effort would finally be sought in putting to use the resources of the Solar system. I wonder if the ETs have a type of Galactic Federation
and what type of role we'd play in it? Since we are very good at breaking stuff and making things that break other things would we end up being
their soldiers and armed forces/police(if they have need of something like that)?
Even being a "grunt" so to speak, would not be such a bad thing if we were able to go off planet and discover strange new worlds and cultures(and
kick their ass:lol

. Makes you wonder about that missing 2-3 trillion dollars from the defense budgets from 2001 and what we are cooking up in the
"black" world.
