Iran is jihadist, so that’s a distinction without a difference.
Iran's jihadism has killed around 300 Americans. Sunnis have killed about 10000. While Iran's nuke program should certainly be destroyed, I can't get too worked up about the Iranian regime's perpetual stream of rants, which don't differ materially from the stuff coming from Sunnis, with one key difference - Sunnis act upon their rhetoric far more frequently than Shiites do.
