Altough U.S.  bad  experience  with Iran  and being ally with Saudies .But to make  a fine  tunning we  have  to accept  that Shia  more  modarate  than Sunna.

Sunna  countries  altough  ally  with U.S. but  as  a society more  anti american  and antiisrael  than shia  countries,thats  why goverment  doesnt  need  to show her  real  face .

Shia  more  modarete and  liberal  than  sunna .Lets  say  today  in saudi arabia  some  muslem  schoolar  books  is  forbidden but  in Iran like fire  worshipercies  ancients religion is offical .Shia  has  more  branch  than  sunna.
