i will make an even more controversial comment, you pointed out about the mess when the likes of hussein and gaddafi are removed and i agree, my observation of the places like iraq, yugoslavia, libya, iran to name just a few is that these countries are so riven with tribalism, political and religious disagreements between their citizens that the only way peace can be achieved and for them to be governed effectively is by a tyrant, this is bourne out by the fact the minute we try to impose western style so called "freedoms" by removing these tyrants invariably the country decends into civil wars and religious, political or tribal genocide.
