Most Dangerous Countries in the world?

The online CIA world factbook lists every country and their respective dangers.

It really depends on the part of the country, and what precautions you take. Countries which are war zones, like Iraq/Afghanistan, would probably be the most dangerous - but most countries have dangerous parts, i.e. malaria in parts of South American, Dangerous animals in parts of Australia. I believe it ultimately depends on the traveller researching their destination and taking necessary precautions.
