What is your position on us involvement in world affairs? should the us intervene where it sees a need, or "mind its own business" and work through international organizations?

I think this requires my opinion so I would say that I would lean on the process of controlled isolationism. The analogy behind it would be like this:

I will not bother you so do not bother me, and if you would feel my wrath if you try and harm me.

Good luck : )
