Not Ready for Democracy?

Despite the loss of credibility the US has sustained over the Iraq and
Afghanistan wars, I think these occupations have raised some very real
questions about whether certain countries in the world can presently
sustain a democracy.  Certainly not all such countries are Islamic but
probably a majority of them are.  What if some countries really can't
become democracies and what does this mean for political science in
the future?
