But if the 1000 was sent at a secret location how did the resistance find out about it that they then sent their T-800? Surely then, since they knew about this event, they would know about the T-1000 - and therefore Kyle's line about the 800 being the 'newest' again makes no sense.
There’s one little factoid that I didn’t touch on that will answer that. In my scenario, the 1000 was sent first from the Area 51 location which is the second location found by the resistance. Only after Kyle is gone, but before they blow the whole place do they discover this location in the NORAD system records.
And then of course theres all the time travel related questions - if the T-1000 went through first then surely, from the point of view up in the future, it should have instantaneously been a success since the past (1995) happened like 34 years ago. And if this isn't the case, if changing the past has no effect on the particular 'present' skynet was experiencing (ie. losing the war in 2029) then why bother with time travel at all?
Let me see if I can straighten this out. This might hurt your brain. You ready…?
I can even do it without totally disregarding T2 and T3. In fact, I can make them even cooler.
Skynet has been sending infiltrators into the resistance with much success, but it still cannot take out John Connor. Somehow John is able to defeat and/or avoid them. The resistance is successfully campaigning toward the NORAD location under the Cheyenne mountains in 2029, but Skynet has access to Area 51 (the government wanted Cyberdyne’s computer systems and engineers to reverse engineer captured alien technology as a side project) and it uses assets there to create a new Terminator prototype using a new mimetic poly alloy derived from alien nano-technologies. Skynet sends this Terminator to the last known location of 10 year old John Connor.
The 1000 could have left an indicator that Skynet would later find letting Skynet know of this attempt at John in 1994, the status of the mission, and the presence of a rogue T-800. Sending the 1000 back would instantly create this information for Skynet to have found. But since John still exists, the 1000 must have failed.
Skynet builds the T-X which has all the capabilities of the 1000, plus advanced weapons and technologies to defeat and/ or reprogram the rogue 800 that the 1000 reported (in T3, the 850 tells John that his (the 850) presence has been anticipated). The T-X fails, but ensures that Skynet happens even though it’s now past due.
Because of the virus upload that initiated Skynet in T3, Skynet knows now about the T-X before it has even sent it, and the presence of John after Judgment Day means that it too has failed. Now, knowing that the 1000 and T-X have failed, Skynet decides to abandon those concepts, and decides to stick with its most successful infiltrators, the 800 series. However, the Area 51 location doesn’t have an T-800 factory, but the NORAD location does, and that is the location the resistance is gunning for.
Skynet knows that any situation involving John cannot end well for Skynet, so it sends an 800 from the NORAD location to1984 to kill John’s mother before he is even born. For this mission Skynet chooses the model 101, the largest, strongest, and toughest of its 800 series combat chassis (built by Cyberdyne based on the remains of said endo found in their factory in ‘84), since it has the highest probability for success.
This is Skynet’s last chance to stop John, but the 800 fails and no record is left as the chip is destroyed and there was no technology available for the 800 to access to leave any info for Skynet to find. The events of ’84 give birth to John, Skynet, and the original timeline again where Judgment Day is August 29th, 1997, and the events of T2 never take place.
By my reasoning there are at least two alternating time loops that have to be occurring within a bigger time loop.
How’s that work for you? Everything is included and works in a believable fashion.
