Radio 4's series on modern warfare and the consequences of global peace.
2:The Arms Trade.United Nations arms embargoes are designed to choke off weapon supplies to the world's bloodiest conflicts. Richard Watson investigates why these international controls are often so ineffective-for example, rebels in Sierra. Leone are selling diamonds to raise funds and using supply routes through neighbouring states to avoid a UN embargo on weapons shipments.
Watson asks why it is so easy for rebel armies and rogue states to flout international restrictions.
