I think the US Administration approach will more or less be "close your eyes and maybe the problem will disappear". That's their favourite modus operandis, as there's too much heterogeneity inside the Administration, they don't really have strategies (wasn't Obama supposed to have a "stronger, broader, etc." strategy "to win" the "war of necessity" in Afghanistan? After all, he doesn't have a clue about what to do, those were just words) or a doctrine about these issues, they are overinfluenced by polls and the President is unexprienced and more comfortabel with words than with actions. I think that in the next 4 years the US will be more comfortable as a follower than as a leader, pretty much like in the late 70s (that's not necessarly bad).
