Yes there is; if you assume you can change the
past by changing the future, then you'll get a paradox. If
they successfully prevent Skynet from coming into
existence, by your reasonaing that would prevent Kyle
Reese and all the terminators from coming into the past,
so they'd never be there, so John Connor wouldn't exist
and Sarah Connor would have no motivation to keep
Skynet from existing.
If you can change any thing in the past, then
there's no reason that you can't change *anything* in
the past.

I guess the context here is 'not understanding what a
