Foreign policy is about diplomacy, not being the bully on the block. The US is perceived as a negative influence in many parts of the world because of our excessive military involvement in those areas. If we reduced the amount of time spent fighting and then building/occupying all of these countries, the negative perception that the rest of the world has of us would diminish. Wars of aggression (Iraq I, Bosnia, Iraq II) only lessen our credibility with the rest of the world (and domestically also) and provide another reason for others to hold us in contempt. A strong military that has the backing of the American public to fight enemies that threaten the US would be more effective and less of a political liability than the military that we have now.
Our military is stretched thin, is too expensive, and is involved in activities that a majority of Americans have no desire to be involved in. Bring the boys home and reduce the military budget by a third.
A foreign policy based on Washington's farewell address would solve many, if not all, of the problems that we face today.
But then, many here would consider the founding fathers to be evil "isolationists".
