Iran has been and continues to promote sectarian violence across the Middle East. It has trained terrorists and militias that have killed and maimed not only our troops in Iraq but untold thousands of innocent civilians. Iran continues to support terrorists in Lebanon, to support the war criminals in Syria, and to destabilize Yemen.
There should be no easing of economic sanctions until Iran stops these activities and pays reparations to victims. There should be no deal that allows Iran a path to nuclear arms. There should be no deal that allows Iran to continue human rights abuses and crimes against humanity against it's own people.
A deal with Iran that does not address all these issues is tantamount to supporting and approving of their crimes.
