The Muslim Brotherhood aren’t Salafi and neither is HAMAS.
And the Shia of Iran are far from allies.
But *we*, the U.S., are not at war with the Muslim Brotherhood or Hamas. We are at war with salafists (and so are the Iranians, who are also flying bombing runs against the Daish — and evidently sharing IFF data with us, since we and they have not had any run-ins over Iraq).
