So you just generalized an entire group of politicians... with what information to back that up, exactly? You do realize that one of the problems with world/american politics is that people have become so immersed in one party in the two party system that they make horrible assumptions and statements like this. Also, to participate in your exercise in mental futility, saying that obama is "way far left" without saying that George Bush is "way far right" is absolutely fucking retarded, and does nothing but show everyone that your opinions come from a very small amount of information and a very select group of sources.
As an aside... Why does America have to "face the rest of the world?" How does it benefit us to set ourselves against everyone else? I'm sure you're going to say "they hate us anyway, so fuck'em".... but how smart is that? If you take a look at why the rest of the world hates us (Maybe it has something to do with our outlandish military and financial support of a nation that has been condemned by the rest of the world as atrocious and dangerously militant), and then consider some ways to fix those problems/repair burnt bridges, wouldnt that bring you closer to a solution that doesn't have us ruining our economy and throwing away hundreds of thousands or millions of lives across the world?
