Secular Arab states, like Iraq, Syria, Nasser's Egypt, Libya sided with the Soviets......Ironically now we would be better off today if those states remained secular.
That's right - the secular (socialist) Arab nations were often pro-Soviet (though Iraq was also a US ally during the Iran-Iraq war), the Islamist states (with the exception of Iran) tended to side with the US during the Cold War, largely because they saw the Christianity of Americans as a lesser blasphemy than the atheism of the Soviets.
