If you look at it from the global perspective: it does not matter much where the oil is dig from: we all live on one planet and the pollution and environmental problems are not easily contained. So from this point of view, it might actually be better to dig wells in the US, where the United States can have more control of how it's done.
However, it might be better to do this away from human settlements, so in places with smaller population density- this might be an argument to not do it in the US, or do it in the places with smaller population density in the US.
Also, doing it in the US would be better for the environment because it would not have to be transported.
Additionally, if US was not dependent on foreign oil, it could lead to less international conflicts and politics could be more focused on actual need of the population of the US - another argument in favor of digging own wells.
- so I just gave some arguments for using own oil, and one argument against it.
