It depends what you mean by dangerous country really?
For health and safety I would say the continents of Africa, not a country just the general continent which is in real need of some help, you can get killed their and life expectancy is really low, people starve to death and it isn't a very happy life to live.
I would say for wars it is America, thinking they police the world when the dont. Terrorism is getting the blame for everything that bad happens in the world, I think Bush made a lot of mistakes and the technology and satellites America has, they could have tracked down Bin Laden years ago, so I dont believe the war on terror, it is sort like a blame thing for me although it does still happen.
