Yes when I was at university I did a module on geographic resource management, and it showed how much planning they did. I was very impressed with the statist methods. I was young and easily impressionable. Holland reclaimed land from the sea and built schools in preparation of children being born now. To implement a plan you need money, how are Muslims going to raise money? Depending on how they raise money whether it is shariah compliant or not, they will be able to bring their plan to fruition. Most Muslims in Syria and the other places you mention would continue with the present system of finance, and with a democracy, therefore we would get countries that operate like other countries already. After a long destructive war, people need to start making things and trading again, only then will they be able to generate savings which can be used to plan and build for the future. Germany after WW2 was completely destroyed, its cities and its people were badly damaged, yet within 30 or 40 years it was a powerhouse of development....much of it was financed by America, yet Britain the winner of WW2 declined even though it had finance from America as well. I do not have the answers.
