[Terminator] In T2 what if Sarah had simply held a press conference and revealed the T-800 (friendly Arnie) to the world? Proof that the robot was from the future and that they can't allow A.I. to control the nukes?

Then at least a nuclear holocaust would be avoided.  Sure, the USA government would confiscate the T-800 and use the technology for better weapons of war.  But America already dominates the world's military, so that wouldn't change.  

And people worldwide might set aside their differences and be awe struck at the wonder of time travel, and billions of deaths avoided....

The problem is, every time you do anything that becomes public knowledge, you potentially create another data point that's accessible to Skynet in the future. If a copy of the article about Sarah Connor's robot survives and comes to the attention of Skynet, there might be another Terminator waiting right where you said the press conference was going to be.
