The first reason is that accidents might occur, it is very unlikely however, there are still chances that the bomb may accidentally explodes, and if that happens, that may kill thousands of people and will affect the area and suffer from radiation and although the chances are low, if a nuclear bomb should accidentally go off, thousands of people may die, and the region may suffer from radioactive contamination. So it is best not to have such a dangerous weapon in your country.
