You can't really answer the question "what are Trump's positions", because he contradicts himself all the time.
Trump has had the most inconsistent campaign I could ever imagine. You name a political position, and he's had it. He's been pro-choice, except he also wants to punish women who have had abortions. He's been pro-gay, except now he's not. He wants to stop getting into wars overseas, except he also says he wants to increase military funding and engagements. He's advocated single-payer healthcare, but he wants to repeal Obamacare and replace it with a "free-market insurance system".
The only thing that he's been pretty clear about the whole time is that he wants to "build a wall". (Though you could even argue he's been inconsistent on his immigration position in other ways).
