No, I think it’s terrible for the United States to be the world’s police.  It’s costly for our country, and it alienates countries around the world who resent our intrusion into issues that are really none of our business. 

In some instances where our national security is threatened, we must act.  In some instances where our allies need or seek our help, we should act.  But in too many instances, the United States does feel that it needs to police the world.  Now, I think that there is a movement from all sides of the political spectrum in the U.S. to reduce that role.  And I do think that there’s a fine line because we also don’t want to be isolationists.  I do agree with what you said — instead of enforcing, we should assist, and we should only do so when our assistance is requested or there is a clear and present danger to our national security or our nation’s immediate interests.
