As Congress votes next month on whether to support the nuclear agreement Team Obama has negotiated with Iran, two assessments are necessary.

One is content-oriented—looking to the four corners of the document to understand exactly what Iran is being allowed legally to do, as well as the impact it will have on our national security.

Fully understanding that, the other assessment is then to analyze Iranian intentions—looking outside the document to determine the likelihood of full compliance by the mullahs.

As Congress undertakes the first assessment, it seems, unfortunately, to pay less heed to the second. But, as the latter demands understanding what the mullahs’ ultimate goal is, in addition to their commitment to achieving it, it is most relevant.

Interestingly, to better understand the mullahs’ ultimate goal, we need only look to ISIS—a group in pursuit of a similar one.

Before we do so, however, consider the following hypothetical: based on what we know about the group today, would Congress even consider negotiating the same nuclear deal with ISIS that has been negotiated with Iran? We hope it would not. The very thought of any agreement paving the way for a nuclear-armed ISIS would be an interminable nightmare for the world community.

The blatant savagery of ISIS undermines its credibility as a candidate with whom to hold nuclear negotiations. A group whose sole creative contribution to society has been to develop increasingly horrific ways of executing victims (and proudly displaying them on video) does not make for a responsible nuclear negotiating partner.

We may have thought the burning alive of caged Jordanian pilot Mu’ath al-Kaseasbeh earlier this year represented the extreme of ISIS brutality. It did not.

We have seen other victims paraded out, hands tied behind their backs, forced to kneel in front of their ISIS captors who—unbeknownst to the captives had buried explosive devices where they were kneeling—move safely away before detonating them. The sight of flying body parts then met with cries of “Allahu Akbar” from among the ISIS savages.

We have seen videos of Arab Christians similarly being positioned and beheaded by ISIS captors.

We have reports of an ISIS leader who, by night, raped his 11-year-old slave girl and, by day, strapped her to the windshield of his vehicle to afford him concealment from snipers as he drives.

The savagery of ISIS knows no limits. Its soldiers, after executing a Muslim father, strapped an explosive device to the baby child he left behind, detonating it to demonstrate to trainees the weapon’s battlefield impact upon the human body.

ISIS justifies its savagery on a Quranic mandate to pursue Islam’s ultimate goal: a global Caliphate by which to rule all inhabitants under sharia–a system of laws stripping its own believers of human dignity and non-believers of their lives.

But it is interesting that the ultimate goal for Islam sought by ISIS is really no different than that sought by Iran’s mullahs.

The brutality of ISIS, the irrationality of its leadership, the darkness that strips it of any humanity, the avowed purpose of its very being–all of this is mirrored within the mindset of Iran’s mullahs. Iran’s mullahs are ISIS wolves in sheep’s clothing.

ISIS is driven by a virulent Islamic ideology, unprotected by state boundaries, seeking to impose sharia upon the world. Iran is driven by a virulent Islamic ideology, protected by state boundaries, seeking the very same global objective.

The two mindsets evolved from one Islamic tree, branching out into different sects following Muhammad’s death. While differences evolved in culture, political systems, eschatological beliefs concerning the “Twelfth” or “Hidden Imam,” the role economics plays, etc., what we should find disturbing is, regardless of which sectarian branch prevails, for us, the end result is the same. Whether a Sunni ISIS Caliphate or a Shiite Iranian one were to dominate, infidels would be forced either to convert to Islam or die–with death imposed by whatever means available.

It is the commitment to an Iranian Caliphate that should concern us more than the commitment of ISIS to one. The mullahs believe for theirs to evolve, global chaos needs to occur–with man a catalyst in triggering it. Thus, providing them with a path for a nuclear-armed Iran gives the mullahs the means to fulfill the prophecy of Islam to which they adhere.

The Western mind rationalizes Iran would never initiate a nuclear strike for fear of retaliation. But the concept of Mutual Assured Destruction (MAD) that prevented a Cold War from turning hot will have no impact upon Iran. Its mullahs see this life as but a means of ensuring their arrival in the next—a paradise of unlimited sexual desires with “recycled” virgins promised by Muhammad. Such is their reward for striving in this life to make the world an infidel-free one.

We see the evil of ISIS by the sins it commits. Why do we fail to see it in the deeds of Iran’s mullahs who mirror them? Perhaps it is because ISIS boasts about its inhumanity while the mullahs are less vocal about theirs.

To fully understand the mullahs’ commitment to their ultimate goal, we need view it through the most innocent of eyes.

The best insight into the soul of a nation’s leadership is examining how it treats its most treasured asset—its own children.

Peering into the soul of Iran’s leadership, one sees only darkness.

As Iran’s mullahs came to power in 1979, the violence against the Shah was soon redirected against their own people, claiming thousands of lives. Some were children who, lacking knowledge about sharia, were held accountable, nonetheless, for violating it and summarily executed. Sharia was to rule over all, even those of a tender age incapable of its comprehension.

For Supreme Leader Ayatollah Ruhollah Khomeini, the sacrifice of children in this life was deemed acceptable to ensure ascendancy to the next. As he proclaimed in December 1979, “Could anyone wish his child to be martyred to obtain a good house? This is not the issue. The issue is (achieving) another world”—i.e., martyrdom of a child is justified in furtherance of Islam.

The extreme to which Khomeini took this was documented during Tehran’s eight-year war with Iraq.

Seeking to reduce Iranian army losses suffered penetrating Iraqi positions heavily defended by minefields, Khomeini issued a call for children to march through these fields to clear a route of attack. Each child was presented a plastic key beforehand, which, Khomeini promised, unlocked the gates to paradise. An estimated 500,000 children were so sacrificed.

A child’s life today in Iran continues to hold little value–children are still executed for acts deemed criminal under sharia. Accordingly, Tehran fails to comply with the Convention on Rights of the Child–an international commitment it made to protect its own children.

The virulent ideology of both ISIS and Iran’s mullahs merge on the common ground they share in totally devaluing the life of a child, evidenced by their unconscionable willingness to use children as weapons of war–whether it be to clear minefields, to serve as suicide bombers, or to execute prisoners.

The mullahs’ willingness to sacrifice the lives of their children should not be lost on us. If they, in pursuit of their ultimate goal, are unwilling to honor international commitments protecting their own children, only a fool can expect them to honor the international commitments set forth in a nuclear agreement.

He, too, is a fool who accepts President Obama’s claim that the Iranian leadership’s cries of “Death to America” are simply made for domestic consumption, ignoring Iranian President Hassan Rouhani’s recent warning, “Saying death to America is easy; we need to express death with action.” If Congress approves Obama’s nuclear agreement with Iran, Rouhani’s wish to replace hopeful words for America’s death with action to achieve it will take a deadly step forward.

Next month’s vote on the Iranian nuclear deal will reveal to us just how many fools we have in Congress.
