There has sadly become a negative connotation with devout muslim due to the Wahhabi/Saudi influence in the world as people seem to feel muslim are bearded nutjobs who don't care about the world around themselves bar their own petty agenda. Should you ever decide to go to Iran even the rural areas you would see how they along with many muslim countries are an absolute exception to that rule much propaganda has been propagated about them which is an absolute crime, in places like Tehran and Shiraz most of the younger generation are extremely western when it comes to their clothing and attitudes in life wheras in places like Mashad or Qom people are more religious but regardless of that i was amazed to see how kind and hospitable they really are and i would recommend you to visit Iran, truly wonderful and enlightening experience.
Iranians in my opinion are the most pro-active muslims and one Pakistanis should learn from, Iranians regardless of their religious affiliations care deeply about their national affairs even Iranian Jews who were offered huge sums of money by the Isreali government to move to Isreal declinded due to their deep affection and loyalties to their land.
USA won't attack Iran, during the 1979 revolution, the hostage crises that followed and during the Iran-Iraq war the country was at its weakest point and they missed their opportunity. Iran now is a different kettle of fish, highly educated population, self-reliant and wealthy it's perfectly situated to be able to cause havoc to USA interests in the region and America is rightly hesistant to prevent any altercations from occuring with Iran.
