The Muslim leaders swallow the advice of the Western powers and bodies like the IMF and World Bank, even when it is bad for their countries and they know this.
You are right, but the weakness does not come from the millions of Muslims in the world. They do not mind being radical, they have no fear to speak out and to protest and to jihad.
Arab leaders worry more about making money from the profits they get from oil and gas that they turn the other way when Lebanon is being destroyed right next to them. Their neighbours are being murdered, but they only make calculations for their own benefit.
