In the 50s we had relations so good with Iran that we helped them build a nuclear reactor and supplied Iran with weapon grade uranium to power it.  Check Atoms for peace.  Then we did a illegal coup on Iran because they wanted to nationalize their own oil.  We put the government we wanted in Iran. That led to the student Revolution and the relations we have today.  
  So now we have Israel and Sherman saying we need to do more against iran.  Israel is the same country that was caught planting bombs on American buildings in Egypt in a false flag attack trying to blame the muslim brotherhood but wa caught. Check the Lavon affair. 
Israel is the same country that attacked the USS Liberty, Trying to sink the ship and machine gunning American sailors in the water.  Our Government ordered the crew of the ship to keep quiet about it.  WE know about it now because of the freedom of information act. Check USS Liberty
  Israel urged us into the war with Iraq,  Hows that working out for America.
