So, its better to leave the tyrants and despots in control?
Things are never quite so black and white.
Consider this, there was far less civilian deaths and the people where much better off when a tyrant was running Iraq then now, after being "liberated."
Is this going to help at all in the long run? That is the intention, but I can't help but think it's going to end up souring them on the idea of western style democracy due to very bad experiences with it.
There may be things that we, as first world countries can do to try and protect human rights in developing countries. But implementing a new system by force is not going to achieve anything, any more then a Communist invasion and overthrow of the US government to "liberate" you and save the workers would in the US.
