America has suffered from a malady of guilt and shame since its Vietnam experience. Whether out of some deep-seated distrust over the use of unilateral American power, or remorse over past American actions, or even some innate pessimism that the use of American military power was somehow malevolent, post-Vietnam foreign policy paradigms came to discourage the use of the American armed force to protect American national interests, favoring instead its use purely for humanitarian missions like the interventions in Haiti, Somalia and Bosnia.
As L. Paul Bremer noted in an interview with Frontline: "The decision to essentially buy our hostages' freedom from Iran was a real failure. We had more American hostages being held at the end of the process than at the beginning of the process, because as soon as it became evident that the United States was willing to pay for the release of its citizens, for every American walking around in Beirut, the price on his head went up. As anybody who's dealt with blackmailers could have foreseen, therefore, the policy failed.....It made us look hypocritical to the people around the world, our allies we were trying to deal with, and of course it made us look weak to the terrorists."
