The self appointed one. Ugh.......
Well, we certainly act like it.
Without us the world will fall into a second dark age we are the Rome of the 21st century the world needs america.
No and I wish the government would realize this.
I think the UN is more of the world policemen, but I could be wrong.
Our government behaves like we are so it can acquire more territory.
It's not our job to go it alone. Though, through our membership to the U.N., we do sometimes bear such a burden. I think, it depends upon who the President is at the time. Warmongers act before they think. Academics think before they act. Pacifists have no place in the Oval Office, because peace (though good) isn't always a reality.
This seems very self-explanatory. Ask Chile, Iran, Vietnam, Iraq, Somalia, etc. Mind you the question was not SHOULD the U.S. be the "policemen of the world", but ARE they. Currently, I would say we are not as extreme in this rhetoric as we were ten years ago, but our history certainly supports the idea. http://academic.evergreen.edu/g/grossmaz/interventions.html
We act like one and every time we help another country we hardly get anything in return. Why? why?
