Personally I think Israel should launch a preemptive nuclear strike against Iran, not just tactical nukes, I mean the high yield H-bombs. I don't believe in fair fight, not against Amalekites who seek to exterminate my people.
Realistically I don't think Israel would dare use nuclear bunker busting bombs. America might but not Israel as it is today. I think most Israelis believe Israel is a helpless satellite of USA, and of course the Israeli cabinet are all corrupt traitors.
