Queen Noor has been making the media rounds for her great new cause — ridding the world of nuclear weapons.

The Jordanian queen, who was born Lisa Najeeb Halaby to an Arab-American family in the U.S. and went on to marry the now-deceased King Hussein, works with Global Zero, a new international initiative working to eliminate the world’s nuclear weapons stockpiles.

Hoping to spread the word, she appeared on Comedy Central’s "The Colbert Report" last night, during which she touted Global Zero’s work — and knighted host Stephen Colbert leader of the Colbert Nation, but not after driving a hard bargain: she required him to sign onto the Global Zero initiative first.

Nuclear proliferation is the "gravest security threat to the world today," she said. Colbert tried to get at which country had the most weapons, but Noor kept her cool.

"But how can we get rid of nuclear weapons — nuclear weapons are what keep us safe from other people’s nuclear weapons?" Colbert asked in his typical snarky style. "Let’s have everyone else in the world give away their nuclear weapons first because we can be trusted — we’re the only ones who have used one. We know how bad it is. We’ll never do it again!"

"That is a Cold War-mindset," she responded.

Meanwhile, the Queen appeared on MSNBC this morning and insisted "nuclear proliferation and the related risk of nuclear terrorism are really the most pressing security threat for nations around the world today." About 40 countries have enough nuclear materials — in addition to nine major nations — to make 100,000 more nuclear weapons that what are already out there. Terrorism is of particular concern, since there have been at least 25 instances of nuclear material theft in the last several decades.

The queen also said she’s heartened by President Obama’s outreach to the Muslim world, and his recent trip to Turkey.

"He has reached out in a way and the use of his word ‘mutual respect’ … it’s vital to relations between any nations but part where the west, and the United States and the Muslim world is concern," she said. But his statements "have to be backed up with outreach," particularly in the Arab-Israeli conflict, she said.
