我想问cripping energy sanctions. "Support for the Green Movement — through the provision of critical communications technology combined with crippling energy sanctions — may well be too little too late to throttle the regime's nuclear aspirations," he said. "But we are fooling ourselves if we believe that what we've done so far will stop the Islamic republic's quest for the bomb." the meaning of vocabulary: 1. crippling: make it damage 2. sanctions: stop trading. My question: 1. It seems the energy sanctions has something to do with nuclear bomb. But what does the energy sanction mean exactly? 2. Why the communications technology with cripping energy sanctions could help throttle the nuclear aspiration? I really appreciate your help. Actually these two questions had taken me half of an hour to figure out. （被删文表示不符版规，请自行查阅版规，「勿」水球版主～） （发文前可将（）内文字按Ctrl+y删除，谢谢合作～） -- --
