I wonder why army of policy maker trainers are not sent to the middle east!!

Dear president obama, 

Like billions of people around the world, I had renewed confidence in revival of American values and improvement In the world when you where elected. This has not changed and I still respect you very much and see you the worlds best change to make it a better place. Having said that I have one question about substance of change of policy from supporting wrong rulers in the past and support for democracy at present. My question is, how could change of a ruler with out change in infrastructure of governance lead to democracy. I can accept that you can not change the culture of the countries like Iraq and Afghanistan but you could at least send some good policy makers to teach him to build an infrastructure for consultation processes and good governance (that by the America is leading in research of). This will have helped to build the foundation to keep the opening you have created by going to these countries and surly all will be lost without such a facility! With due respect and Kind regards Matt Wishful
