should america have a strong dollar or a weak dollar?

When our dollar is strong than we can buy more foreign goods but the more we spend overseas the less we spend here. if we have a weak dollar than importing goods like oil will be more expensive. so it is a game of give and take. It is hard to say if i would rather have a weak or strong dollar because there is good and bad arguments to both. I think that i would rather have a weak dollar so that things here at home wouldn't be so expensive.
