I've come to the conclusion that it may be best to have a foreign policy where we start from the stand point of non intervention, where we start from the perspective that we shouldn't intervene overseas, and then only support intervention in rare circumstances, when we really have no other options. I'm just not convinced at this point that a strict non interventionist foreign policy is realistic. For instance, what if Iran were to close down the straight of Hormuz? If that happened, the price of gas would probably go to $20 a gallon. That would directly affect U.S national security. No one could afford to travel. It would destroy our economy. I think that non intervention is the way to go 98% of the time, but we still have to examine each individual situation and see whether or not it's realistic to do nothing. The vast majority of the time it's realistic to do nothing, and the vast majority of the time doing nothing is the best option. But it may not always be. But in the rare situations where we have to intervene overseas, I think Congress should have to approve it, there should be a clear objective and goals, we should go all out and complete the objective, and then get out and bring all of our troops back home. We should never indefinitely occupy a country and use our military for the purpose of nation building.
