The deep partisan animosity in Washington, DC is disturbing enough when it blocks things like fixing Social Security or the air traffic control system. But it is uniquely dangerous when political wrangling messes up America's relationship with the rest of the world.
Back in the old days (long before my memory) differences between Democrats and Republicans were supposed to stop at the water's edge... meaning that when it came to shaping U.S. foreign policy all Americans recognized a common interest and worked together to promote a united front.
That all seems a little quaint in today's political environment. Is it still possible to forge a bipartisan, moderate foreign policy?

Does the USA have a relationship with the rest of the world – clearly not if you look at US veto’s of unanimous UN votes.

Everyone but Americans, and certainly every international diplomat knows the USA is an international pariah state.
Why doesn’t the US media tell the US public that?
