After most of the planet had already been nuked in a Nuclear fire. THAT"S ONE HAPPY ENDING!
Look Darth, I'm just not buying your argument. There's nothing you can say to convince me that the entire point of T2 was the Judgment Day was inevitable. A film where they continuously tell us there is NO FATE and spend most of it trying to change to course of history.
What was the point of blowing up Cyberdyne? Or Miles Dyson's heroic sacrifice? Or even Uncle Bob's heroic sacrifice at the end of the film, when he's lowered into the lava, so nobody would ever be able to continue Dyson's work and cause Judgment Day.
All of that is completely UNDERMINED, if you look at the film with the mentality that it was all for nothing because JD is going to happen regardless.
