SilentSurfer,
I still cannot see how you believe only two timelines are represented in the movie's when we have 3 different Terminators traveling back in time along with one human.
There may be more than two timelines because of time incursions made in three different movies, yes, but we have only seen two of them represented. T1 is a loop. T2 threw off the loop, and all events and sequels have taken place in that timeline. The TX certainly changed something by killing off John's Lieutenants, but we have never seen that future or heard about it, except that the T-850 had killed John and Kate was his wife, and their children will become important. Now that I've said that, you are right. There were three timeline represented, the missing one involving members of the Resistance who since T3 did not live to see the war begin.
Superman said:
As for there being no Skynet at all if the original Terminator hadn't come back in time and left his chip and arm behind?
My observations lead me to believe Cyberdyne and Skynet the first timeline around did occur without the aid of the Terminator chip left behind. However it took at least 10-15 years longer for the T-800 design to be created without having the chip being left behind and studied by Dyson. Now go 40 years into the future and Kyle Reese is a part of the resistance, older than we know him, and learns about the T-800 being sent back in time (for a different purpose than T1, (probably to make sure skynet occurs more quickly) so he must go back after it. (This Timeline happens before T1 since Kyle does not know Sarah yet) So Kyle goes to the past to stop Skynet so Judgement Day doesn't occur. At that point John Connor shows up in the womb of Sarah Connor thanks to Kyle and the rest is history.
Here is another version of how the older Kyle goes back the first time. Same as above however Kyle goes back to the past alone in order to try and stop Judgement Day altogether by destroying cyberdyne and skynet. No Terminator infiltrator is sent back in time yet because they (skynet) were winning the war the first timeline around. This is where Kyle Reese meets Sarah, tells her about Judgmemnt Day and she gets pregnant. John Connor is born and already knows about Skynet through Kyle and his mother so they have an advantage now to stop them. This then leads skynet to send a T-800 back to kill Sarah for the first time. John in the future knows the timeline has changed so he has to send his father (a younger version of him which he gives his mom's picture to so he subconsciously falls in love with her as they were destined to be in whatever timeline) This causes the film Terminator 1 to occur. The fallout of Terminator 1 is that John survives, but Dyson and his team get a hold of the T-800 chip and arm so they cut back how quickly it takes to create the T-800 by about 10 years.
Now either pre-Terminator 1 story fits. It doesn't matter which one you choose, or you can invent what you like. However something must have happened before Terminator 1 was sent back and it is not irrelevant and should not be overlooked when trying to explain things. The chip from the T-800 in Terminator 1 left behind and the arm only are there to speed things up. The machines were going to be built by the same companies one way or another thanks to Government funding and research.
The key point you are missing is that the only known use for the Time Displacement Equipment was for Skynet to use it to ensure that Sarah never gave birth to Skynet's downfall, John Connor. If not for Skynet's plan to stop John from being born, the TDE would not have been made, and your whole thing about Kyle going back to prevent Skynet, or to do anything else, couldn't even be a consideration. If not to stop John in the past, for what purpose was the TDE? My position is based on what we KNOW from what we've all SEEN. Anything else is just making ____ up.
Besides, if Kyle's 'original mission' was to just stop Skynet from happening, and there is no Terminator, what's the catalyst that convinces Sarah to hook up with this freak from the future? "Hey, good lookin', I'm from the future. Do me." Sarah was scared of Kyle. If not for him saving her life TWICE, she would never have trusted him. She sure as hell didn't believe his story about the future, even after seeing the 'other' guy get up after being shot and set on fire. Why would she believe him now.
There's a whole subcontext to T1 that you aren't seeing. Cameron wrote a love story. Kyle loved John enough to die for him. Kyle also loved Sarah, 'the Legend', enough to travel through time to face off against a Terminator with only primitive weapons. "I came through time for you, Sarah. I love you. I always have."
Kyle valued women by their ability to fight.
"What are the women in your time like?" -Sarah
"Good fighters."
He would have greatly admired Sarah because of the stories John had told him about her, how "she taught her son to fight, to organize..." She was the woman who made the man he most admired. Kyle admitted to knowing no women romanticly, and there would have been no woman he idolized more.
"John gave me a picture of you once. I didn't know why at the time."
But John did. It wasn't just so he'd by chance run into Sarah, and maybe they might have sex after Kyle stopped Skynet's creation. Kyle told Sarah that he looked at it all the time, studied every curve and every line. Kyle fell in love with Sarah through John's stories and that picture. Sarah would have told John that, and that's why he gave it to Kyle.
Ensuring that Kyle saved Sarah was only part of Kyle's mission, the only part he was aware of, the mission Kyle VOLUNTEERED for.
"I volunteered. It was a chance to meet the legend."
But the other part, the part John would have had to be 'grooming' Kyle for discretely is, was to ensure that Kyle fell in love with his mother, so that Sarah would fall for him, and John would be born. It was Kyle's love for her and her son, and his sacrifice for both of them that moved Sarah to give herself to him. If not for that, some soldier from the future who had no experience with women, would never have managed to get into her pants.
To understand what Cameron was really doing in T1, you have to understand the characters he created. The movie wasn't just about a robot and soldier and a waitress. It was a love story set in a sci-fi genre. That is why it was brilliant, and that is why your theory, Superman, has no merit. I'm sorry.
