If you think Fox and MSNBC define the right and the left ... then you really are a clueless American. What passes for 'left' in America is pretty severely to the right in the rest of the world.
And precisely why would I give a fuck what is "right" and "left" in other parts of the world?
If I wanted to live in a left leaning, more socialist part of the world, I would.
I prefer the US.
I will agree, the US and its polices aren't the "good guy" ones of the past, I blame that on corporate money takeover of our govt.
But I don't really care what the world thinks of us. I really don't, I have too much of my own life occupying my time and efforts. I don't have time to waste worrying if country X doesn't like me really, as long as they leave me alone and don't throw a weapon at me.
I do think if the US *did* pull fully out of world politics and wars...there'd be a lot of screaming that "the US doesn't do anything, they don't share, they don't help"...etc.
Hell, if we pulled fully out of all the bases and all in Europe, there would likely be a lot of pissed off people when they found they had to start pulling all that funding for free healthcare and 3 month vacations in order to pay for their own self defense in the big bad world. The US covers a lot of your countries' defense cost allowing you to spend your money on other things.
