prime minister netanyahu has said, hold out for a better deal. everybody would like to see a better deal eventually. but the question is, when and how you get there. is it immediately or is it step by step? he said, do not lift restrictions until iran stops its aggressive behavior. the only actual restrictions on iran's nuclear program are under the current interim agreement. the rest, of course, are sanctions and there is no lifting of any sanctions at the moment. that causes the iranians a great deal of pain in these negotiations and there's been very little lifting under the interim deal. beyond that, the u.s. and israel both want to make sure that iran does not become a nuclear power. israel wants to do it by denying any capability and the united states and the allies want to do it by persuading iran not to exercise that capability and not to produce any nuclear weapons. so that's where the difference is. >> let's go up to capitol hill
