Who instigates a campaign against the families of the abductees? Those who have no achievements to present - voila! news. The status of the families is the same as the status of bereaved families.
The citizen can only turn a deaf ear, politely listen to their cry, nod, feel their pain - and then act according to his conscience and faith. If the demand is a final and absolute ceasefire, with international guarantees that will guarantee it for years to come - then there is nothing to talk about.
