I imagine that foreign policy is one place the Obama administration will shine, especially given that much of world already seems to like him, and he hasn't even done anything yet as president.
One of the biggest stumbling blocks for Bush has been the "I'm going to take my ball and go home" approach to just about any nation that torques us off in the slightest. It's either that or "America never negotiates with ___".
It works some of the time; I firmly believe the line has been forever and too deeply crossed with al queda, they've proved in other areas like Iraq they're there just to stir up crap and really don't give a damn about even the Arab community they've sworn they're defending. There should be no negotiations with them, not a one, not ever, for 9/11 alone, until they're just extinct cockroaches.
Other nations that have a legit point of view, even if we don't like them, fine. I'd like to see Obama go to Pyongyang, Tehran, Havana...show them that the US isn't scared of anyone but will at least sit down and talk with them.
Other things I heard are encouraging too; he wants to create a lot of jobs here by developing green technologies; that's killing two birds with one stone and we all know that both have to be done (or we've just got our heads stuck in the sand).
