1. Democracy is a great system, perhaps the best system for governing a country ever invented by man.
2. What can be better than a government of the people, by the people, for the people. And most of the developed countries are democratic, obviously benefiting from the system.
3. Does this mean that all countries which are governed democratically will be stable, prosperous and developed? The great democracies of the West seem to think so. Such is their faith in the system that they are willing to kill and destroy in order to promote democracy. They have now decided to bring about regime change in order to democratise the undemocratic countries. If you resist democratisation they will kill you and destroy your country. And so they did in Iraq and are doing so in the Arab countries and elsewhere.
4. It is assumed that the people, or at least the majority of the people would be wise enough to choose the most capable people to rule them. Unfortunately the people do not always choose the most capable. They may be influenced by race, religion, ideology and a host of other factors when electing their governments.
5. They may also choose because of money. In fact in most cases their choices are based on immediate personal gain rather than national interest.
