Disagreeing with Iran being the largest terror threat may also be agreeing with Pat Buchanan, John Bolton or others. I don't see Iranians cutting off the heads of Christians, others in the Middle East whenever they can, every day.
Iran is Syria's big ally, a regime many people see as being the lesser evil vs. ISIS.
You don’t see them doing this? Just go to Iraq, then. Or Mexico, even.
Iran and its proxies have killed thousands of Americans. “Death to America” is essentially a national motto, chanted in its parliament. And they are developing nuclear weapons and ICBMs. They are a threat in a way that ISIS is not. And they are responsible for ISIS. The Iranian-dominated Iraqi government treated the Iraqi Sunnis horribly, cutting them out of power and bringing in Iranian advisors to train the national army into an anti-Sunni sectarian front. The Sunni Arabs were pushed back into the hands of what had been Al Qaeda in Iraq. But AQI operated out of Western Syria with the aid of the Ba’athist Syrians. Iran and Syria are not the counters to ISIL but it handmaiden. Each uses the other for an excuse to gain power thank to Oabama’s weakness and delusions.
