What can the West do to avoid wars like in Iraq and Afghanistan in future?

What can the democratic West do to avoid such absurdly unsubstantiated and extremely risky wars like in Iraq and Afghanistan in future? What's fundamentally wrong with the existing mechanisms of democratic control in the Western countries that could allow such wars to be started in the first place even in countries like UK where about 80% of the population were dead against the Iraq invasion? UK - parliamentarian democracy - plunged into Iraq war a couple of years latter only because it's PM for some absolutely unknown reasons individually decided to do so - how come?!

¶ Ban weapons and manufacturers, go back to natural energy sources, and so on... Keep away everything that could make wars profitable to some individuals.

I don't know if its possible at this point in time. Our way of life as it is right now is dependent on oil and as long as that is threatened we will poke our noses where by all rights it does not belong.

Take care of our own people and let them take care of themselves.
We don't need to force every country in the world to be like we are.
