But if you're asking specifically what I would do, well, the question you've posed is very abstract so it's hard to get clear what you're really asking.
What sorts of scenarios, where it's my close relatives vs people on the other side of the world, are you thinking of?
It's often not a zero-sum game, and often the popular perception of it in zero-sum terms is vastly overblown.

Regarding your clarification, I can not think of any scenario where I would want something done that would benefit my close relatives at the expense of people in other countries. I'm open to you suggesting some possible scenarios.
