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.

The price of oil and inflation are connected in a cause and effect relationship, that is, when the price of oil increases, inflation also increases in an economy. this is because, oil is a major input in the economy, that is, it is used for critical purposes such as fueling of vehicles for transportation, for running of industrial generators and machines, for heating homes, etc.for instance, if the price of oil increases in an economy, it will increase the cost of production for those using the oil in their production processes and they will automatically increase the cost of their products in order to offset the extra costs. this leads to general increase in the prices of products in the market and result in inflation.
