Regardless of administration, the policies of the United States concerning humanitarian intervention have been disappointing. There are no distinct advantages for American citizens and often the outcome for the victim/aided country is negative.
We are going in to fight wars that cannot be legitimately won. Instilling democracy has almost never been successful from a unilateral, foreign actor.
The best we as Americans can do is protect our self-interest, while encouraging the grassroots rebellions for democracy in Middle Eastern and African countries, without intervening to the point where our policies become counterproductive.
