Marco Rubio has argued that Iran is controlled by
“radical Shia clerics”
who supposedly believe it is their religious mission to bring about the end times — and that this makes an Iranian nuclear weapon uniquely dangerous.
There is a serious theological problem with that argument.
Twelver Shias do believe in the return of Imam al-Mahdi. But believing in the Mahdi is not the same as believing Muslims must manufacture an apocalypse to make him appear.
Classical Twelver sources actually warn against attempting to determine when the Imam will return. Al-Kafi, one of the oldest major Shia hadith collections, contains a section condemning the fixing of a date for his appearance. Historical scholarship describes much of the traditional approach during the occultation as waiting with patience, not deliberately creating global catastrophe.
That is the crucial distinction Rubio’s argument misses:
“Shias believe the Mahdi will return.” — Yes.
“Shias are religiously commanded to start a world war so that he returns.” — No established Twelver doctrine says this.
Christianity has the Second Coming. Sunni Islam also contains extensive end-times traditions. Religious belief in a final divine intervention does not automatically translate into a state policy of deliberately destroying the world.
There is another contradiction in the claim.
Iran’s highest religious authorities have publicly maintained that nuclear weapons are forbidden under Islamic law. Whether one trusts Iranian policy or not is a separate geopolitical question — but this is hardly evidence of a clerical doctrine commanding Iran to acquire nuclear weapons and ignite Armageddon.
And none of this means Iran cannot be criticized over enrichment, missiles, regional armed groups or its confrontation with Washington. Those issues can be debated using intelligence assessments, military capabilities and actual state behaviour.
But turning belief in Imam al-Mahdi into a doctrine of deliberately triggering the apocalypse is not an accurate description of Twelver Shiism.
Iran can be ideological without being suicidal.
Believing in the Mahdi does not mean believing humans must manufacture Judgment Day.
If Washington wants to argue that Iran represents a nuclear danger, that argument should stand on evidence about nuclear capability and strategy — not on a theology that Shiism itself does not teach.
