That's a year after ID4, which gives time for the world to rebuild and the invasion isn't as fresh in everyone's minds. I'm pretty sure many cities were totaled in that film.
Regarding "Outland":
The Con-Amalgamate company from Capricorn One is mentioned in this film.
Polydichloric Euthimal, a fictional chemical from this film is mentioned in both "Terminator 2: Judgment Day" and "The Middleman" "The Palindrome Reversal Palindrome".
