Spreading democracy

How are we spreading democracy? Are we right to spread democracy will it always work? I am not sure if the war in Iraq was a triumph or a tradegy? Was the real reason for capitalistic gain? Look at Afghanistan the same issue but more difficult to assess, control and dominate. Bosnia is it better off today then it was in the early 1990's. I am not sure what the political aim was but it definitely makes people wealthy, the security companies, the defence companies the governments that take the taxes. It is the same with claiming we are saving money buy buying goods from emerging markets but the major countries that supply the development money must have an incentive to get pay back! But not with China the beta blocker. This country is developing the new form of democracy based on communist leadership and hierarchy.
