Trump's offer to Kasich (as confirmed by Kasich himself) was that he would be the quote 'most powerful VP in history', in charge of both domestic and foreign policy, while Trump would be in charge of 'making America great again'. So the other poster is exactly right, Trump doesn't have anything at heart beyond self-aggrandizement.
You might reasonably expect that Pence was made a similar offer. If that's how it played out, you could probably expect a relatively vanilla foreign policy from Pence.
The problem is there's no guarantee that's how it would play out; Trump is narcissistic and unstable. He might actually intend to do that until Pence does something he doesn't like, and then Trump takes the reins back.
If all you care about is foreign policy, maybe Pence is okay with you. The guy is a garbage person though and made me ashamed of my home state on multiple occasions.
Pence is actually also a terrible choice and even people in Indiana don't like him.
For the record I'm not a Trump fan either. I'd like to reform some stuff like patent law but Trump would burn most of it down.
I'm just saying that ~in theory~ Pence is an olive branch towards the middle. I don't think Trump will follow up on it in any way, nor will he be elected given the polls.
