"I don't think that anyone seriously fears that the world can be blown to pieces all together. But what one can fear and rightly so are regional things, like in the Middle East, India, Pakistan, the Korean Peninsula, borders in Africa, etc"

Hans Blix is suggesting that while the world as a whole is not likely to be destroyed, there are still many areas of the world that are at risk of conflict and destruction. He specifically points out the Middle East, India, Pakistan, the Korean Peninsula, and Africa as regions that could be impacted by local disputes. Blix is warning that these areas are especially vulnerable to conflict and destruction, which we ought to be aware of the capacity for violence in these areas. He is also suggesting that we must take steps to prevent dispute in these areas, as the repercussions might be ravaging. By recognizing the potential for conflict in these areas, we can take actions to prevent it from happening.
