Question: In the second film, the T-800 stated that Skynet launched the nuclear missiles in response to the government trying to shut it down. This is not the case here (as John states that Skynet has little-to-no-chance of being destroyed by conventional means). It just preps launching them as soon as it becomes active. It is not longer motivated by any clear threat to its existence. What, then, causes Skynet to identify humans as the enemy and initiate Judgement Day?
