 Targeted individuals cannot visit their wives, children, relatives, or families without severe risk, and may even avoid their names being made public for fear of being killed.Israeli killings of Hamas leaders Yassin and Rantisi for example, caused Hamas to not publicly identify their replacement, a step necessary to ensure his survival.Continual diplomatic pressure against the Israeli policy, and the announcement of temporary cease-fires at various times by Hamas are seen by some as further proof of the policy's efficacy.
