Failing states can infect a whole region  It is in the interests of international stability that failing states are rescued before it is too late. Failed states often infect a whole region, as the collapse of Liberia did in West Africa - a problem known as contagion. Neighbouring states back different factions with arms and squabble over resources, such as the diamonds of Sierra Leone and the mineral wealth of Congo. Internally neighbours are destabilised by floods of refugees and weapons from next door. Their own rebel groups can also easily find shelter to regroup and mount fresh attacks in the lawless country just over their borders. Former U.N. Secretary Boutros-Ghali claimed, as his justification for support for failing states, that the U.N. has a responsibility under its Charter to ‘maintain international peace and security’ amid fears ‘the demise of a state is often marked by violence and widespread human rights violations that affect other states’. [1] Intervention prevents this by entailing the establishment of conditions for reconstruction which thereafter provides physical infrastructure, facilities and social services. The ultimate goal therefore of the intervention is to ensure that both the state concerned and the region as a whole require no further military or monetary support. [2]  [1] Ratner, S.
