When Bad Theology Starts a War: Ted Cruz, Genesis 12, and the Road to Iran

How a Protestant misreading of Scripture may lead America into a catastrophic holy war

Senator Ted Cruz believes the United States must support modern Israel, unconditionally, militarily, even preemptively against Iran, because of a single verse from Genesis: “I will bless those who bless you, and curse those who curse you.” In his eyes, this is a geopolitical strategy, authored by God.

Cruz stated it bluntly in his interview with Tucker Carlson. When asked why America should support Israel in striking Iran, even if it meant regional or global escalation, Cruz appealed not to prudence, nor to U.S. self-interest, but to Genesis 12. “Those who bless Israel will be blessed,” he said. End of story.

This is not a marginal view. It’s a core conviction of American evangelicalism, particularly among its political class. Members of Congress, presidential advisors, and even Pentagon insiders carry this belief into their policy calculations. But the tragedy is this: they are wrong.

Genesis 12: Not a Foreign Policy Manual

The passage Cruz invokes was spoken to Abram, personally, as part of God’s covenant with him and his descendants. It was not a blanket policy for Gentile nations in 2024. It certainly wasn’t a divine endorsement of whatever geopolitical entity calls itself “Israel” at any given point in history. The modern state of Israel, founded in 1948 by secular Zionists, many of them agnostic or atheist, is not a theocracy, not the Old Covenant nation, and not a valid fulfillment of biblical prophecy.

The Church Fathers knew this. Saint Paul, writing in Romans 9, makes it clear: “Not all who are descended from Israel are Israel.” The promises of the Old Covenant were fulfilled in Christ and extended to the New Israel: the Church. “If you are Christ’s,” says Galatians 3:29, “then you are Abraham’s offspring, heirs according to the promise.” The Church, not a Middle Eastern nation-state, is the inheritor of the covenant blessings.

Yet Cruz and his fellow Christian Zionists turn this upside down. They read Genesis as though the U.S. must serve modern Israel, or else suffer divine wrath. That’s dispensationalism, a 19th-century heresy barely older than Mormonism.

From Bad Theology to Real Bombs

Cruz insists that supporting Israel means preemptively destroying Iran’s military and nuclear infrastructure, even decapitating its leadership if necessary. He suggests regime change could be justified and even hints at America’s possible participation in covert sabotage or strategic strikes.

At no point does Cruz show concern for prudence, proportionality, or just war principles. When Tucker Carlson presses him on the likely blowback, the millions of civilians affected, or the possibility of igniting World War III, Cruz waves it all off. Why? Because in his worldview, those who bless Israel will be blessed. And those who don’t, those who question whether modern Israel’s every military act is just or wise, are essentially inviting a curse.

This is theological malpractice with nuclear consequences.

Israel Is Not the Church. Iran Is Not Amalek.

No Catholic, or any Christian grounded in historic tradition, should be fooled. God’s plan does not run through tanks and bunker-busters. Our Lord did not say, “Go ye into all nations, and support their airstrikes.” And while Cruz may sound pious invoking Scripture, his interpretation is Protestant prooftexting at its worst: isolated, literalistic, and politically weaponized.

The U.S. has no divine mandate to support a foreign nation no matter what it does. The Church teaches no such thing. And to suggest otherwise, to claim America’s safety and blessing depend on unquestioning support for Israel’s military campaigns, is blasphemy disguised as patriotism.

Conclusion: Foreign Policy Needs Fathers, Not Fundamentalists

The real danger isn’t just Ted Cruz’s ideology. It’s how widespread it is. His view of Israel and Iran is shared by powerful men in both parties, shaped by Protestant revivalism, Cold War Zionism, and the fantasy that America is a second chosen nation.

But America is not ancient Israel. Washington is not Jerusalem. And the Ayatollah is not Gog of Magog. If our leaders cannot separate Scripture from sensationalism, they will lead this country, and the world, into catastrophe.

It’s time we stopped letting bad theology write our foreign policy.
