Should america have a smaller and less interventionist foreign policy

Yes

Explanation:

Looking at the forty years of U.S. military action in the Middle East region, we should conclude that the presence of American military cannot change the political orientation and structure of other societies. For instance, the United States has failed to influence the actions of sectarian actors in Lebanon, failed to change Iranian foreign policy even after decades of relative military encirclement, and humiliated themselves by just watching Saddam defy Washington and violently cracked down on Kurdish and Shia uprisings.
